I have a phpbb3 forum currently on 3.2.8 version running on php5.4. But this version doesn't run on php 7.3. So, I need to update/upgrade (whatever it is called) to 3.3.0 version. Some of the files are modified but nothing too serious.
I will supply you the database dump and the forum folder zip. You need to load it up on your system, update it, and give me back the updated database dump and the folder zip.
I will load them on myserver and test it out.
