The variable $whitelist does not seem to be defined for all execution paths leading up to this point.

				if(FileHandler::exists(_XE_PATH_ . 'common/tpl/sitelock.user.html'))

The expression \FileHandler::exists(_XE_PATH_ . 'common/tpl/sitelock.user.html') of type string|false is loosely compared to true; this is ambiguous if the string can be empty. You might want to explicitly use !== false instead.

TRUE is of type boolean, but the function expects a integer.

The expression $url of type array is implicitly converted to a boolean; are you sure this is intended? If so, consider using ! empty($expr) instead to make it clear that you intend to check for an array without elements.
