Thanks, yeah this actually helps a lot.

I didn’t even think about mod\_security, but now that you mention it, I *have* seen it quietly wreck stuff in the past, especially on shared hosting. Gonna check if that's active. Also, the idea of disabling all non-core stuff and re-enabling one by one... I'm definately gonna try that. I just kinda assumed "J5-ready" meant safe, but clearly not.
About PHP, I’m on 8.2 right now, but maybe I’ll roll back to 8.1 and see if things stabilize a bit. Haven’t touched the session settings yet either, so that’s going on my list.
The media issue is mostly with PNGs, yeah. JPGs upload fine. Could be a missing image lib like you said—I'll check if GD or ImageMagick is fully loaded.
I’m running this on a small VPS. It's nothing fancy, but it should be solid. Still wouldn't be shocked if there's some sneaky config thing messing stuff up.
Really appreciate the tips. Kinda reassuring to hear others have been through the same stuff. Anyone else had similar issues or found other workarounds that helped?

So I just did a clean install of Joomla 5 on a new server (PHP 8.2, MySQL 8), and I’m already running into a bunch of weird issues right out of the gate.

A few things I’ve noticed:

Installer said everything was fine, but after login, I got a blank admin dashboard until I cleared cache manually

Language override screen just loads forever

Media manager randomly breaks when uploading PNGs

Some extensions throw errors even though they claim to be J5-ready

I mean, maybe I missed something basic during setup, but this feels kinda rough for a fresh install.

Anyone else dealing with these kinds of things on new Joomla 5 sites? Could it be hosting config stuff, or just bugs that still need ironing out?

What to look for or what you usually fix right after installing?
