There was a 500 error out of no where.

The front end works fine, however, I am not able to login.

Removed the .htaccess file and checked, still no avail.

Help please!

EE 2.11.1 PHP 5.6.13

  • It might sound strange, but when I switched the ISP, the 500 server error went away. I am guessing it has something to do with the DNS.

It seems there was a change in EE 2.11 that caused this. CSM was using a method of extending/hijacking a core class to get this to work, which has been fine for the last 6+ years, but no longer works. If you really need to use CSM you’ll need to downgrade to 2.10. Otherwise I suggest just uninstalling it.

I’ll work with EllisLab so I can restore the functionality to CSM, however, I wouldn’t expect anything to happen in the next week or two.

Sorry for the troubles, but I’ll post updates here when I get them.

You can now download version 2.6 (it is packaged with the EE3 version 3.0.2). If you’re using EE 2.11, which is causing the problem, you will need to make a core hack. See the README file. This change will be in EE 2.12 so you only need to make this hack once.

Hope that helps!


Try disabling extensions. In your config file add:

$config['allow_extensions'] = 'n';

You can also individually turn your extension on/off via your installation's DB.

To address the actual issue: I'm experiencing this same issue today and I've narrowed it down to Custom System Messages.

I'll report back when I find a solution.
