The issue is that we can not use the buttons in the econa custom field anymore. Joomla flips to the article list view and the article is locked. When I turn of the JCE plugin the econa plugin works again. I suspect it's a javascript issue? Also, when the JCE plugin is disabled (JCE Editor Pro - Administrator-Component) the close button of the article stops working. Not sure it that is related.
This is only an issue on Joomla 3.
Joomla! 3.10.11
JCE Editor Pro - 2.9.37-rc2
PHP 8.0.28
