Внимание!
При проверке ваших PHP-скриптов на совместимость с новой версией PHP ($VER) были обнаружены фатальные ошибки. \
Текст ошибок представлен ниже. Если указанные файлы используются в работе вашего веб-сайта (или его части), \
то скорее всего после обновления PHP ваш сайт (или его часть) перестанет работать.
Чтобы обеспечить работоспособность этих скриптов вам нужно будет их скорректировать (или, если возможно, \
обновить их до версии совместимой с PHP $VER), либо обратиться в службу поддержки и запросить перенос сайта \
на сервер со старой версией PHP.
