Blank Page During Update at Configure Database Step

Hi guys,
This issue has been driving me crazy. I’m trying to update to the latest version of Invoice Plane, the setup runs fine up until the configure_database part, at which it displays a blank screen. Attempting to log into the system still displays the old version number.

We are currently on CentOS 5, PHP 5.6 and MySQL 5.6. I’ve already tried the different database.php config trick of mysqli and mysql which doesn’t seem to resolve the configure_database issue. However, on mysqli I just get blank pages across the entire site.

Any ideas?
