I'm using Tiki Admin > General Preferences (button: reset or upgrade your database), but each time I do this, it only offers to update to 12.4, nothing higher. I go through the whole process, but nothing changes, still on 12.4.
- recently upgraded to a virtual private server (from shared hosting), there we have 4GB memory (though it seems it's not set up properly)
- tried to find the php.ini file to change the php memory limit, no such file exists
- no longer have Softaculous as on other sites I just use this to update and works great (in changing from shared server to VPS we los Softaculous, have to sign up separately now).
