i can't login to my admin panel

[josazee]

Go to your configuration file via FTP or cpanel
Make sure the permissions are set to write 644
Open the configuration.php file
find
public $lifetime = '720'; (Note: your may have other value here)
public $session_handler = 'database';

Change to this
public $lifetime = '720'; (Note: your may have other value here)
public $session_handler = 'none';

LEAVE YOUR CONFIG FILE OPEN AFTER SAVING CHANGES
Now go log into your Joomla admin panel and stop. Once you have logged into your admin, go back to your config file and change the none back to database. That it... now go log back into your admin panel again and your fixed.

Don't forget to make sure your configuration.php permissions file is set back to 444

Regards

This worked on joomla 1.5 not logging in to admin backend and not displaying error message.

SOLVED, Thanks

I had the same problem when I changed the setting to "Memcache" while messing with Cache Settings. It took me straight to the website when I logged in to the admin and would not allow me to go into the admin panel to make changes. After removing the word 'memcache' from configuration.php in my legacy file system, the admin panel suddenly worked again where I was able to turn caching off. When I rechecked configuration.php it had be reset to no caching and all was well. I was able to log back in.

Here is where it said 'memcache' in the configuration.php file:

Where it says 'cachelite' is where 'memcache' was so I just deleted it and left the apostrophes.


public $caching = '0';
public $cache_handler = 'cachelite';
public $cachetime = '20';


Thank God I came here first before starting over!

Hello

I tried every solution on this thread but to no avail.

When I'm login in, the http:// goes to https://

Is it normal ?

[gigowattfilm]

I managed to log back in. I thought I would post because it is not in all the solutions of this thread.
Since the login would redirect to https after I press enter, I found the route.php file in
libraries/joomla/application/route.php.

I edited the 0s (default) to 2s in that line :
if (!is_array($url) && (strpos($url, '&') !== 2) && (strpos($url, 'index.php') !== 2))

It did the trick !

I still have issues, because if I try to edit back the login_module_form back to normal (ie encript login form to no), then I cannot log again. (Good thing I have another computer logged in...)

Hope I'll never have to get stuck like that ever again...

I have the same problem with joomla 3.4. Was working on things, creating articles, etc. Then today it says my user name and password don't match or I don't have an account yet. Now I'm completely locked out of my site. I didn't find my user name and pass that I type in the back end in the php, but there are other user info which I tried and it didn't work. I created another superuser and that didn't log in either. Authentication is enable, cookie is this:
public $cookie_domain = '';
public $cookie_path = '';
For the xxx_sessions, do I delete/truncate everything thats in there? Or how do I purge it to see if that helps?
Also, how do I disable caches? Is that something in the php?

[railer]

I fixed this issue by myself. It is a cookie issue. it might be a joomla 2.5.4 bug.
I modified configuration.php file in root directory by deleting 2 line below.

public $cookie_domain = 'YourCookieDomain';
public $cookie_path = '';

Hope this solution is useful.

I just deleted the values. Worked for me when not being able to login in J3.4.1. Silly me for setting the two values. What was I thinking. Thanks Amosin!

[RustyJoomla]

I had the same problem, but fixed it by removing the entry for the cookie_domain in the config file.

Example:

public $cookie_domain = 'YourCookieDomain';
public $cookie_path = '';

and making it like this

public $cookie_domain = '';
public $cookie_path = '';

worked and was able to login right after making this change. I had been logged in for about 9 hours before the login stopped working. I was coming back to it the next day when it had stopped working I hope this helps track it down..

This worked for me on an old site I need to migrate to J 3.x Thanks for the tip!

Hello everyone,

some help to a desperate user is needed.

So I can't login into my admin panel even as a super user.

There was a write log error, so I changed the configuration.php. Then there was a Ldap problem and I disabled it (set it to 0 plg_authentication_ldap). Then it was said that password and username didn't match. So, I changed the password taking care to put an MD5 function. still nothing. Finally it is said that I am not allowed access to the management area of this site. I checked all the permission stuff (authentication etc.) They are all enabled. Moreover, I changed the log and tmp permissions to 777. Still nothing. Help will be appreciated

Using 3.4.1

I modified configuration.php file in root directory by changing 2 line below.

public $cookie_domain = '';
public $cookie_path = '';

Worked for me.

If you have a authentication problem read this: https://docs.joomla.org/How_do_you_reco ... assword%3F

I removed the value I had set in the cookie_domain variable and was able to login, such a relief.

“Cookie Settings” Group

Only present in Joomla v1.6.x and later, these settings allow the site cookies to be modified to suit certain circumstances. For the majority of web sites these entries may be left blank.

https://docs.joomla.org/J3.x:Global_configuration . Circumstances when to use cookie are explained. Just leave empty in general

The cookie domain may be useful if you want a cookie be valid for several subdomains. The cookie path would have to be set if the cookie should only be valid for a certain subdirectory.

Hello

I'm facing the same problem (cannot log into administration, simply getting back to administration with no error) + front-end returns a redirect loop;

Tried everything posted on this thread (all 3 pages) with no success. Cache, cookies cleared, did all changes in all combinations in the configuration file, checked the .htaccess file, phpmyadmin etc. and still nothing that helps. Deactivating the language filter plugin returns blank page in front-end instead of the redirect loop (well.. 404 if I leave /dk in the URL).

My domain name includes ø by the way. But I made sure that the tmp and log paths are written properly: xn-- as prefix and -bnb, also removing that special character.

I've just asked my host provider if he has different session handling options as I've enabled errors from config file and I'm getting the following errors:

Warning: preg_replace() [function.preg-replace]: The /e modifier is no longer supported, use preg_replace_callback instead in /var/www/xn--xxx-bnb.dk/public_html/libraries/joomla/filter/input.php on line 652

Also how I encountered this problem: switched from a domain name to another, migrating all my files and my database. Did that before with other Joomla setups but I've never encountered any problems. The only difference is ø in the path. Everything was perfect before transferring.

Hoping for any kind of hint and will try any suggestion; I'm a front-end developer with some experience in back-end, PHP and OOP as well. Can handle mysql and 've been working with joomla for 4 years now.

Many thanks and best regards,
Dan

I managed to login but i see only white
any advice?

[kazyfake]

Possible solution.......

This message is for newbies who like me may be stumbling along with huge gaps in their knowledge - learning by doing but not necessarily understanding what they are doing ......

I had this problem and still don't know what caused it, but after changing my username and password in my database (via cpanel & phpmyadmin > ..._users), I still couldn't login. I tore my hair out in frustration, combing this thread and the web for suggestions, trying everything I could find, then discovered that if you change your username in the database, DON't use MD5 to encrypt it - only do this for the password.

This worked for me. I hope it helps someone else.

I tried everything posted here, finally fingured that something must be wrong with the user because it says the entered data either does not match or I do not have an account (and I did have the admin account in myPhpadmin) so after a few hours of troubleshooting I changed the password to MD5, entered the password in the 'password' field, saved, and it finally let met in.

Thank you!

I had this same issue, I could not login, the admin page refreshes anytime i tried to login. After trying all the solutions above without success, i changed the PHP version in my hosting account from PHP 7 to PHP 5.6 and was able to login

[vilaycl]

Hi, I have a problem with this too.
I change my computer, and now I try to log in with the same password and username as always, but I can't log in, it says "Warning

Username and password do not match or you do not have an account yet."

I need help with this, it's so urgent for me enter to my administrator site!!!!

[bodyoflight]

I have been trying so many different things - and have not yet been able to login to my admin backend for some time now...

I am not sure if there are some extensions that are interfering/causing this problem that may need to be disabled? And if so how do I try doing this through PHPadmin backend?

If there is anyone that might be willing/able to help take a look at what is going on - I would greatly appreciate it.

[pe7er]

Did you try to create a new Super User account via this method: https://docs.joomla.org/How_do_you_reco ... assword%3F ?

When you get the same error with the new Super User account then one of your authentication plugins might have been switched off.

You can switch it on using phpMyAdmin (Create a backup of your site (files + database) before doing so!).
In your database table #__extensions you need to change the value for the field "enabled" from 0 to 1 for these plugins:
plg_authentication_joomla
plg_user_joomla

I had the same problem and after checking all suggested here, I read some where that it might be the php version offered by my server! I check in my website's Cpanel and changed it from 7 to 5.4 and worked!

That is impossible with Joomla 3.8.x. See minimum requirements https://downloads.joomla.org/technical-requirements

Joomla 3.8 does not work with PHP5.4. Your reply is inaccurate to say the least. Besides that Php5.4 is obsolete and Joomla 4 which is coming relatively soon will require PHP 7.1 the least or it won't work either. If something does not work in PHP7.1 it will be caused by incompatible versions. Follow my footer links as example. All the sites mentioned are running (with all extensions) PHP 7.1.13. So no complains. Your server is badly configured or you have incompatible extensions if something does not work
