I have already completely uninstalled and reinstalled the extension. But this did not help. I get the following error.
0 Layout "manager_popup" not found in Paths /var/www/virtual/vnv-urbex.de/joom4_vnv-urbex_de/htdocs/components/com_jce/editor/libraries/views/plugin/tmpl
System:
Joomla 4.0.5
JCE MediaBox 2 - 2.1.2
Editor - JCE 2.9.18
PHP-Version 8.1.0
EDIT:
After clicking on "back to the dashboard", the backend is displayed in the popup.
Unfortunately, I can't get on without help.
Many Thanks
