Hi,
I've just installed the JA Purity IV "Quickstart package" on my server. Everything seems OK on the front-end, and I'm able to login and edit my profile. But when I access the back-end (example.com/administrator), I get the following error:
An error has occurred.
0 Class "Joomla\Module\Login\Administrator\Helper\LoginHelper" not found
It's a fresh new install of the "Quickstart package" that I downloaded today on your site. My PHP version is 8.2. I had successfully installed Joomla 5 before on the same server and everything was working fine. Not sure what's going on. Please can you help?
Obs: It's a fresh new install. I deleted everything on the server before (existing files and previous database).
