Problem!

Hello Problem with activating the theme, blank page. The Flexiblecustom module seems to be the cause. I disabled (by changing its name) to activate the theme. when I deliver the right name to the module, again with a blank page [PrestaShop] Fatal error in file Module :/var/www/vhosts/xxxxxx.net/xxxxx.xxxxxx-.net/modules/flexiblecustom/FlexibleCustomFastCache.php: Uncaught exception ‘PDOException’ with message ‘SQLSTATE [HY000]: General error: 23 authorization denied’ in /var/www/vhosts/xxxxxxx.net/xxxxx.net/modules/flexiblecustom/FlexibleCustomFastCache.php:1891 Stack trace: # 0 /var/www/vhosts/xxxxxx-web.net/xxxxxxxx.xxxxx-web.net/modules/flexiblecustom/FlexibleCustomFastCache.php(1891): PDO-> exec (‘VACUUM’) # 1 /var/www/vhosts/xxxxxx-web.net/xxxxxx.xxxxxx-web.net/modules/flexiblecustom/FlexibleCustomFastCache.php(1520): FlexibleCustomFastCache :: initDatabase () # 2 /var/www/vhosts/xxxxxx-web.net/xxxxxx.xxxxxxx-web.net/modules/flexiblecustom/FlexibleCustomFastCache.php(431): FlexibleCustomFastCache :: pdo_cleanup (’’) # 3 /var/www/vhosts/xxxxxx-web.net/xxxxx.xxxxxx-web.net/modules/flexiblecustom/flexiblecustom.php(11): FlexibleCustomFastCache :: cleanup () # 4 /var/www/vhosts/xxxxxxx-web.net/xxxxxx.xxxxxx-web.net/classes/module/Module.php(1243): require_once (’/ var / www / vhosts. .. ‘) # 5 /var/www/vhosts/plateforme-web.net/gian
