If I try to install Acymailing Starter 8.8 in J4.4. I get the following error message:
Unable to reach the site. The web page at https://www.waterwind.it/demo/administrator/index.php?option=com_installer&view=install may be temporarily unavailable or has been permanently moved to a new web address.
Do I have to switch to J5 first?
I have already Acymailing 7.9.5 installed on my site.
