After migrating a website from Joomla 3 to Joomla 4 and installing SOURCERER PRO v 9.5.2 I get the following message: Error: Sourcerer cannot function. Regular Labs Library plugin is not installed.
Several times I have deleted the folders
/plugins/system/regularlabs
/libraries/regularlabs
and also deactivated/ uninstalled the plugin. Nevertheless, after reinstalling Sourcerer Pro, the familiar error message comes up.
I thank you in advance for your support in this matter and send you access data in the Confidential Area.
