Answered Suddenly Fatal Error. No login-in in manager

Hey,

the site ist up for a while and until know everything was fine.
Today I want tu update some content. But when I call the manager URL I geht this error:

Fatal error: Call to a member function getMessage() on a non-object in /www/htdocs/wCCCCC/core/model/modx/modmanagercontroller.class.php on line 623

What can it be?

The first thing to try is deleting all files in the core/cache directory and clearing the browser cache and cookies.

If that doesn't work, I've seen similar reports caused by the host upgrading PHP.

It's also possible that the host has made some other change (e.g., file permissions or changes to session handling), but those are less likely.

Hm...you say that it can be something with the file permissions.

A few days ago I changed the file permissions from a "subfolder" that has nothing to do with modx.
It could be that it is what cause the problem.

The problem ist still there. What can I do to solve the problem?

I try to delete this files within the cache folder. (it is not possible to delete most of the files, because of permissions)

That's odd. Did you try deleting them on the files tab in the MODX manager?

I can not login into the manager, because of the error message.

So, can it be with the permissions? The "FTP-User" and the "PHP-User",
Is there a list, what Folder und Subfolder from MODX should be associated to the specific user?

Hm. Ich checket the permissions and it seems that have nothing to to with them.
What else can I do? Run Setup again?

Running setup again is always worth trying.

You should be able to remove the core/cache files in cPanel or the equivalent.

What version of MODX are you running? Some of the early 2.x versions suffer from cache corruption, which can cause your symptoms (and can be fixed temporarily by deleting the core/cache files).

Also, check the version of PHP that's running. Your host may have upgraded to a version of PHP that's incompatible with your MODX version.
