Upgrade from 3.1 to 3.2 Fatal Error in Administrator Page

[sovainfo]

Don't know whether it is needed next time. You might even restore 3.1 and update to 3.3. First try without disabling. You could also update 3.2 to 3.3.

Sofar, the actual cause of the issue has not been identified AFAIK. You might want to try https://github.com/joomla/joomla-cms/pull/3467.

OMG I was in pain. I managed whit the method

rename remember.php -> rename joomla.php -> create table -> fix db

But now I have the backend layout totally mixed up.

Why!?

[adriespo]

b) Search and install missing plugins

Sorry, what do you mean with "search"? Manual search?

I think I miss some plugin because the layout of backend is confused...

[adriespo]

Well, I can answer to me

The last step was to Discover and Install all plugins and templates missing, then select isis as backend template.

Here is my solution
Rename your file remember.php to rememberBAK.php so it looks like this
/plugins/system/remember/rememberBAK.php
Find a copy of Joomla 3.1.15 and make a copy of the remember.php
FTP the file to your folder
/plugins/system/remember/remember.php
Now access your admin panel
Go to Extensions -> Extension Manage -> Database
Click Fix
Now go to ftp, delete the remember.php that you uploaded and rename the original one to it's correct state

Joomla updates do not update the database and this needs to be done manually.
For not developers, the above method is the simplest and quickest way

Good luck

Thank you so much, your solution solved my problem and I was able to upgrade finally to 3.3.1

For those still dealing with this issue, get the 3.1.x files here:

Joomla version 3.1.x downloads

How do I disable the remember me plugin?
It's greyed out, and marked with a lock icon (for protected).

[sovainfo]

Go to Extensions->Plugin manager
Search for Remember and click on status to disable.

Hey sovainfo.

That's what I'd usually do, but the plugin is protected (greyed out and marked with a lock icon) and I can't click on it. Clicking on status does nothing. Is this unusual behaviour? What can I do to disable it?

[sovainfo]

Think you are confused with Extensions->Extension manager->Manage!
For some reason you can not disable protected extensions there, use Plugin manager!

Thank you Hazza and PeterSW! Worked perfect.

I had the same problem. I couldn't fix the database. So, if you get the error on the "Fix" database option you should create the table "xxxx_content_types" in your database (mySQL) by the following SQL query:

CREATE TABLE IF NOT EXISTS `xxxx_content_types` (
`id` int(11) NOT NULL,
`content_history_options` varchar(5120) NOT NULL COMMENT 'JSON string for com_contenthistory options'
) ENGINE=MyISAM DEFAULT CHARSET=latin1;

where xxxx is your dbprefix in your database, e.g. 'd3hrs_'. You must change xxxx to your dbprefix!!!

After that the "Fix" database option should work!

[sovainfo]

No, it doesn't!

Read the whole thread and you'll know why!

I try to install autotrweeting but is not working and i uninstall one, log out. Next day i have same error via admin "Class 'FOR Platform' not found in " I try to change remember.php - not help.

So for me works:
I find same Joomla version what i have (3.2) and just rewrite "fof" folder in the /libraries/fof
and it start working!

Just my suggestion please backup a original fof folder (in case)

Good luck to everibody
