Hi all,

I have installed modx on an external server, and all was fine, but when I logged in today - something very strange happens.  
If I try and edit a resource, chunk, TV - ANYTHING - I get a flash of the element on the screen, but then it goes white - leaving just the butons top right (Save, Delete, Duplicate, Close, Help!).

If I click ANY of those buttons, the resource/chunk/TV etc is restored, and I can carry on editing - any ideas what could be causing this strange behaviour?

Running the latest version of MODX (2.8.3)  
PHP version: 7.4

Thanks!  
Andy

Just found the issue - it was the plugin called ‘VersionX’. I disabled all plugins, and re-activated one by one. Shame because I use that extra regularly - but for some reason it doesn’t like my installation!

Hi @tm2000 ,

Would you be able to see if there’s anything related in the MODX / PHP error logs when the plugin is enabled?  
If there’s a 500 error it should show what’s going wrong there.

Thanks - This is the error i get in the logs when the plugin is activated:

But further to this issue, Migx isn’t working - if I create a Migx TV, and try to populate it in the resource, I get a blank screen again. Everything else seems to be working fine.

Very strange!!!

I have just reinstalled versionX and it’s still throwing the blank screen, but no errors in the error log

Could it be a permissions issues maybe?

Are there any errors in the console of the developer tools of your browser?

There seems to be a “500 Internal Server Error”. These errors aren’t logged in MODx. There should be a _PHP error log_ somewhere on your system. The exact location depends on your server configuration.  
Can you search for this log file and post the exact error message.

The MIGX connector creates a JS error which leads to the further errors. Maybe some MIGX TV is configured wrong.

I believe you should add it to the top of the connector php file. `https://dev.domain.com/assets/components/migx/connector.php` (for MIGX) or `https://dev.domain.com/assets/components/versionx/connector.php` (for VersionX).

OK thanks - I have aded it to migx - but no error is shown on screen. I just have a white screen with the ‘save, duplicate,delete,view,close,help’ buttons.

Ths is the error in developer tools:
