Bad login results in 500 internal server error

Post by ant_000 » Mon Dec 12, 2011 12:34 pm

Hello,

One of our website running on J! 1.7.3 seems to be working fine with both .htaccess and SEF enabled.

We came accross a very strange issue when providing an empty or bad combination of username/password and clicking login (by the way, we use the core login to handle or logins)

In both cases, joomla returns an http "500 internal server error" on http://www.domain.com even though this is the main url to access the site (our login module is placed on the main page) Following a few hours of investigations, I figured out this might be linked to my .htaccess file (posted below)

I tried to comment FollowSymLinks but didn't seem to work (instantly anyway) ..

I'm not a .htaccess guru.. could anyone advise? hope this post will help a lot of other people who seem to have similar issues.

Dear all,

Maybe I ough to mention this apparently important information: my website is using godaddy. Could this have an impact on the content of the .htaccess?

Hi, thanks for your feedback.

Yes SEF and mod_rewrite is enabled on backend
I tried commenting out Options +FollowSymLinks but we didn't notice any difference

I tired through Firebug to anaylize the code of the login module. the module apparently sets a token that is passed through when cliking on login. When deleting this piece of code, I receive the bad login error.. but when leaving the code unchanged, as it should, I get a 500 back.

Any ideas?

I tried various .thaccess files, including the one mentioned in another post:

http://forum.joomla.org/viewtopic.php?f=618&t=594932

But still I still get the internal server error when providing an empty or wrong login on the front end.

Could this be linked to permissions? Been stuck for days on this issues, thanks for any feedback

I have the same problem. To me it looks like on failure it is simply trying to go somewhere "bad" (such as somewhere restricted by an .htaccess file, perhaps).

Is there a way to set the page Joomla directs to on failure?

Thanks,

T

I got the Solution!

Steps:
1. Check the log and temp folders permission. Set it to 755 if not set.
2. Open configuration.php
Now you need to change the values of the variable
$log_path = 'XXXXXXXXXXXXX';
$tmp_path = 'XXXXXXXXXXXXX';

To absolute path of these folders on your server. In my case i am using cPanel. So values would be
$log_path = /home/****/public_html/log
$tmp_path = /home/****/public_html/tmp

:pop :pop :pop

I had similar problem.
Dunno why u change permissions - it's 0444 and what i had to do is: your step #2 - changing paths.
Then I did just what http://duckprince.[URL banned].com/2012/02/ ... rator.html says - rewrite password in database - no need to contact hosting company, no need to change security settings
(dunno much bout permissions and security issues but I've found some info about changing permissions to 0644 in this case - maybe it works 2).
I'm wonder if it can stay the way it is without further problems.
cheers

(folder) logs 777
(file) /logs/error.php 777

nothing less.

last time i had this server error problem, i notice in the error_log it says memory allocation limit reached, so i just allocated more memory in my php.ini from 45MB to 55MB and it worked just fine.

Thanks for the input. Please also note that for me worked fine only when I put the same path (/web/htdocs....logs & /web/htdocs...tmp) used in configuration.php also in the joomla admin panel (Global Configuration --->System and ----> Server)

Temporarily change logs folder permission to 777.

Submit blank or bad Login (goes to error message).

Change folder permission back to 755.
