[~] Fixed some severe bugs that have been introduced in version 1.9.1

How to update:
For Version 1.9.1: Simply replace the web panel files (you can keep your config.php)
For older versions: Due to the changes in the database schema, this version is NOT compatible with the database from older versions. If you are already using AdvancedLicense on an older version and want to keep your data it is recommended to stay on the old version as the 1.9.x updates have neither security nor feature changes.
