Work:PHPBB-3.0.3 Bug

There has been a bug identified in PhpBB that causes the forum administrator unable to log in to the Administrator backend. The bug appears to only be relevant to version 3.0.3. Please note, this bug has not been fixed as of Nov 28th, 2008 but a test installation of PHPBB3 on my own server functioned fine.

The Errors

The customer is getting errors like:

[phpBB Debug] PHP Notice: in file /includes/functions_admin.php on line 2405: array_fill() [function.array-fill]: Number of elements must be positive

When trying to login to the Administrator Panel:

The Fix

Open: includes/functions_admin.php

Find (Approx line 2403):

    if (substr_count($log[$i]['action'], '%') - sizeof($log_data_ary))

Replace with:

    if ((substr_count($log[$i]['action'], '%') - sizeof($log_data_ary)) > 0)
