Strange MODX behaviour!

tm2000 · September 9, 2021, 1:22pm

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!!!

tm2000 · September 10, 2021, 9:29am

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

tm2000 · September 10, 2021, 9:45am

Could it be a permissions issues maybe?

halftrainedharry · September 10, 2021, 9:52am

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

tm2000 · September 10, 2021, 9:55am

hadn’t thought if looking there - yes there is when I try and add a migx item:

And this is the error when versionX is installed:

XHRPOSThttps://dev.domain.com/assets/components/versionx/connector.php
[HTTP/2 500 Internal Server Error 240ms]

halftrainedharry · September 10, 2021, 10:04am

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.

tm2000 · September 10, 2021, 10:21am

Hmm I only have acess to cPanel - I can’t find any error logs in there at all. Nor in the file manager.

jako · September 10, 2021, 10:23am

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

halftrainedharry · September 10, 2021, 10:29am

Maybe this post helps to locate the error log.

tm2000 · September 10, 2021, 10:43am

Thanks - I thought so - but I have taken a migx TV form a working site to make sure but it’s still a problem.

tm2000 · September 10, 2021, 10:47am

Thanks so mcuh for all this advice. So I foudn an error_log file, but it’s empty.
I will try adding the PHP you supplied - shoudl I just add that a a snippet on the same page?

halftrainedharry · September 10, 2021, 10:54am

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).

tm2000 · September 10, 2021, 11:00am

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:

halftrainedharry · September 10, 2021, 11:34am

I’m not sure if this even works for AJAX-requests.
Maybe you can open the “Network”-tab of the developer tools in the browser and then click on the XHR-request that generates the error and check the response. Maybe there’s something useful in there.

tm2000 · September 10, 2021, 11:47am

hmm - thanks again!!

So in there there is a 500 error for Migx:

Could that be a permissions issue?
