I spent the better part of today installing a phpBB forum on a new site (specifically phpBB 3.0.4). This was my first experience with phpBB, and it looks pretty cool. I won’t cover the install process here — there are plenty of great resources available for that — suffice it to say that it was very easy to install.
Once I had the software installed, I wanted to make some modifications to the header — include my own logo, etc. This should have been easy, it’s just a matter of editing the overall_header.html file (download file via ftp, edit in text editor, upload, refresh). But…no matter what I did, I couldn’t get my changes to show. After quite a bit of time, I found a solution in a forum (yes, ironic).
To hopefully save others some frustration, I’m re-posting it here. The key is that you need to refresh your template before the changes will show on the site. To do this:
Go to Forum ACP->Style Tab->Template->Refresh your Template
That’s it! Wish I would have known a few hours ago
