[Solved] Enabling Advanced File manager broke my backend

[Lenndor89]

Hi,

I just enabled the advanced file manager mode and checked the "make thumbnail" option. When the page refreshed, i lost the content of that page and the rest of the backend pages. The main nav is available and it does changes to the pages i click on. But it doesnt show the content of the page.

I have no idea how to fix this problem. The website is still online but i can't do a thing in backend. When i go to the "Content > Pages" it goes blank. Edit: It gives Error code "500". Only on this page. but i have no idea what to fix. Tried debug mode, but couldn't find a thing.

I hope that there is someone that can and wants to help me.

I am using CMSMS 1.11.7.


Thnx in advance

P.S. I did search the forum for a (similar) post about this problem, but couldn't find it. So if there is a post already, with a solution, plz tell me.

Check your server error logs if you can and also potentially restore from a backup. If you are referring to TinyMCE for advanced file manager try deleting that module.

Failing that post a request in the Help Wanted (Commercial) thread.

Caution: things could get worse if you don't know what you're doing.

If you have access to the database (phpMyAdmin for example) you could try to revert your changes:

Had a look into a backup sql file of one of my sites and found this relevant line (note that I use 'cmsms' as table prefix):

Code: Select all

INSERT INTO `cmsms_siteprefs` VALUES('FileManager_mapi_pref_advancedmode', '0', NULL, NULL);

Then, you might also have a 'FileManager_mapi_pref_create_thumbnails' entry, but in my sql file it does not exist (maybe because it's not set).

Error 500 MAY BE caused by too 'high' permissions (like 777) on specific module (sub) folders. In this case I would suspect the 'modules/FileManager' (sub)folders. 755 permissions could be more appropriate (applied to subfolders recursively)

Hi,

Thanks for the fast response. This is the kind of solution i was looking for. I found the "file manager advancedmode" row and changed the value it into a 0. Now it works again Got my CMS back. didn't change the thumbnail value, so I could find out what the cause was, and it was the advanced mode value, apparently.
Did panic a bit when I noticed that the site couldn't connect with the database, caused by the fact that i changed the database user Password. I restored this to the old one and it worked again.

SO thanks again!
