New install of 3.2 front end admin area blocked

[simonprestney]

I have a few sites with Joomla 2.5 and now 3.2 but my most recent site seems to have an issue where the front end goes blank when I try to log in as adminsitrator. The error message is:-

Fatal error: Call to a member function isAdmin() on a non-object in /home/recruite/public_html/jobsboardglobal.com/plugins/authentication/cookie/cookie.php on line 51

Any ideas?

In terms of third party extensions I have added they include:-

RokMenu, Akeeba Backup, eXtplorer, JCE Editor, Maximenu, Add This, Gantry Framework, Gantry Template, Addprint stylesheet, Captcha is enabled.

Has anyone any idea what could have caused it?

Line 51 states the following // No remember me for admin
if ($this->app->isAdmin())

I have the same problem after installing a new template, Gavik "Music Free". So Now I can not reach my admin login. Only a blank screen with the error text as a text line in the top of the page.

Every idea is very welcome!

After adding Gantry Framework for a template that I installed (rt_leviathan) I have been getting the same error trying to log into the back-end,

Fatal error: Call to a member function isAdmin() on a non-object in C:\xampp\htdocs\joomla\plugins\authentication\cookie\cookie.php on line 51

Any information on the error would be greatly appreciated.

I need to get this working!! I have a deadline for this site and I cant work on it!

Same problem. I had 2 versions of the same site running under Wampserver. I upgraded one of the versions to J3.2 and noticed that my customer Jquery routines running on form fields in a Chronoform were no longer working. I then copied the J3.1 scripts from the online version of the site:http://clubaero.nl/en/formula/survey over the upgraded offline version and the JQuery scripts in the forms are now working again. But now I cannot login into the dashboard of the offline site version - I get the fatal error message:

Fatal error: Call to a member function isAdmin() on a non-object in C:\wamp\www\CA311\plugins\authentication\cookie\cookie.php on line 51

BTW I have already posted a question about this problem in a new topic - hope I am not breaking forum rules about double postings?

Wish I could post an answer but instead have to post a +1 on this. In my case, I have been trying to upgrade from 3.0.2 to 3.2.1. I first run into the known remember.php error and after replacing it with 3.1's remember.php, I then get this exact error.

Here are my FPA results:

Error after upgrade to 3.2.1

I confirm the same issue on 3.2.3.
But blank screen is only for wrong username/password combination. I can get in with correct password.
I am in a process of installing a template - could this break Joomla?
Weird.

ps. Also, after installing a template Joomla thinks it is 3.1.1... and suggests to upgrade. Although it 3.2.3 installed. It is probably template's problem?

[mackdoyle]

dang, I cannot remember how I fixed this issue. I think I:
1. Manually overwrote my system files with a copy of 3.2.23 via FTP.
2. Edited remember.php as outlined http://joomlacode.org/gf/project/joomla ... m_id=32568.
3. Cleared my browser cookies and logged into the admin.
4. Once I got into the admin, I went to System -> Clear Cache and cleared the cache.
3. Went to Extension Manager -> Discover and clicked the [discover] button.
4. Went to Extension Manager -> Database and clicked the [Fix] button.
