My backup installation of miniBB still works fine except for the original issues.
No one can register as they get:Error in user data: Unable to register new user. Possibly username or email already taken, or admininistrator info isn`t filled, yet
And when I am logged in (as Admin) I can not goto my prefs as I get:There was a database error. Please report this problem (what you were trying to do etc.) to boards administrator, or contact the authors
If I was to do the above I would also need to simply remove the 'prefs' & 'register' items from the main header.
This is the only way that my BB will work ok as far as I can see....
I know that my installation of apache2, php, active perl, and MySQL are fine as I have no other issues with any other scripts etc...
All the above applications are the latest versions too.
At one point I even tried going to an old version of apache and php but it was the same...
