Blank page when trying to create a forum

[cesagonchu]

After creating a category, I get a blank page when trying to create a forum (modules/bxpress/admin/forums.php?action=new) and no errors with debug mode.

So, I inserted this code into forums.php:

if (PHP_VERSION_ID < 50400) error_reporting (E_ALL | E_STRICT);
else error_reporting (E_ALL);
ini_set('display_errors', true);
ini_set('html_errors', false);
ini_set('display_startup_errors',true);
ini_set('log_errors', false);
ini_set('error_prepend_string','');
ini_set('error_append_string','
');
ini_set('ignore_repeated_errors', true);

and I finally get an error:

Fatal error: Class 'RMFormImageUrl' not found in
/modules/bxpress/admin/forums.php on line 121

Yes. bXpress needs from AdvancedForms to work properly. I'll add a warning to prevent this issue.
