Okay, /forum from 2.0.22 to RC1 is not working.
but I have successfully been able to set up a test board and update that from /testforum 2.0.22 to RC1 /forum3
- RC1 phpBB3
So the process works on my server, that's good news. It struck me that maybe something with my current board is not quite right, I have updated it often with changed files only so maybe /forum is not 100% as designed. So what about copying phpBB2 database to another database? Or setting up a new phpBB2 board that uses the same one and trying that? Or maybe doing a fresh phpBB install to my current board?
Any of those ideas worth a punt?
1. Copy database to new database (not sure that'll do anything new though)
2. Start new phpBB2 forum with fresh install and link to original database (maybe using concept 1)
3. Reinstall 2.022 over my current files.
Edit: I think 3 is essentially the same as 1 & 2 in combination and less risky, how does fresh install compare to change files only?
