After installing Component, Plugin and then Module from todays new downloaded Joomla3 version the following message appears:
Warning : constant(): Couldn't find constant JPATH_ in / ((mydirectory)) /libraries/src/Installer/Adapter/ModuleAdapter.php on line 214 {"success":true,"message":null,"messages":{"message":["Die Modul-Installation wurde abgeschlossen!"]},"data":{"redirect":"\/administrator\/index.php?option=com_installer&view=install"}}
What is the error and what do I have to do? Can I use the Module in my joomla installation?
My configuration is:
PHP-Version 7.3.6
Webserver Apache/2.4.41
PHP-Interface für den Webserver cgi-fcgi
