I try to install acymailing on Joomla 4 but I got this message "Refresh Manifest Cache failed: Acym Extension is not currently installed." The component seem installed when I look at the ftp directory but it doesn"t appear on the admin panel. What"s wrong?
Please follow these steps and check if it resolves your issue.
I saw this explanation on the web but it seems to be for joomla 3. I don't see The button "Purge cache" in the extensions manager or "database fix" .
But with this points:
-Go to Extension Manager -> Discover -> Discover.
-Install the found modules/extensions/plugins.
It seems to be good, now I see Acymailing.
You're welcome, enjoy your Acymailing.
