If you are using a gantry based template you may experience a white page on the front end. If error logging is set to maximum you will see an error message:
Error loading error page.
If you just see a white page please set Error Reporting to Maximum in your Joomla server configuration to make sure this is the same problem.
This rather cryptic error message is caused by a conflict between the twig library used by Pbbooking and the twig library used by Gantry.
This error can be corrected by using ftp or cpanel file manager to delete or rename the twig library with pbbooking. This is located at /libraries/purplebeanie/twig.
Simply removing or renaming this folder will prevent Pbbooking’s version of twig being loaded and use Gantry’s version in all cases.
