phpBB 3.0.11 to 3.0.12 Update Tutorial
Note: phpBB 3.1.X is now out. I believe updating to 3.1.X will be the same? But use this tutorial to update to any phpBB version above 3.0.12 at your own risk all the same.
When some of the mods(called "extensions" in 3.1.X) that I want to have, are updated to be compatible with 3.1.X I will update and make another tutorial if I am able. I'm pretty sure I will be doing a fresh install and importing my database.
