I ran into this a while back when I first came to use phpBB and I remember it driving me crazy back then. I did manage to fix the problem but until now, I never needed to install another forum...
Basically I've created a database in mysql, called 'forum'. This means that my forums will be located at http://www.mysite.com/forum/ - so far so good.
I then created a user to access this database, which, again went well. The user name is 'samurai' with all permissions set.
Next was the installation of phpBB. A folder was created called 'forum' in the correct place and phpBB was installed into it via ftp.
I can access every file fine via ftp.
Now when I go to install the forums using the built in phpBB installer, this is where the shit hits the fan...
Here's the screenshots:
As you can see I've put the correct info in the right fields but I'm still getting these errors no matter what I change or alter.
Does anyone know how to fix this?
I know there's not a problem with the installation or any of the files so it's not that.
