[Solved] Blank WYSISYG edit screen with JCE

After updating an installation to 3.3.1.5 I get a blank screen when using a WYSIWYG editor (TinyMCE) on Joomla 3.9.4

Also, I cannot reach the Dashboard or configuration screen with the TinyMCE on.

WYSIWYG editing works OK in other (non flexicontent) areas.

Debugging is not telling me much, but Chromium reports a 500 server error.


Flexicontent editing works if I switch to a non WYSIWYG editor.

Any help, anyone?

Thanks

The issue seems to be a custom date field.

We can create a new article (event type) that has two custom date fields.

As soon as we attempt to edit the date the editor hangs. In Opera and Chromium a 500 server error is notified.

In firefox the page stays blang

Hello

MySql / PHP version on the server ?

Also please enable Joomla Debug to see if you get a full error message

Using PHP 7.2

I have debug on, but when going to edit on a flexicontent article the screen is just blank (Firefox). There is no debug info. Page source is also empty.

In Opera the debug info is visible. When attempting to edit a flexicontent article with TinyMCE I get

domain.com is currently unable to handle this request.
HTTP ERROR 500

We can edit flexicontent articles when using CodeMirror or the Acymailing editor.

Thanks

This from our server "Unhandled Exception" logs'. NOt sure it's related, but the date thing looks suspicious and the time corresponds.
