Now I have the brand new installed phpBB 3 forum. In the final step of installation, I click “proceed on to convertor” to start converting the phpBB 2 to phpBB 3.
Remove the install folder to access the full forum function.
11) After some test and I decided to replace the old phpBB 2 forum by this phpBB 3 forum
SSH to the server.
rm -f -r forum.g2soft.net
mv fourm3.g2soft.net forum.g2soft.net
