[Webdome]

Hey all,

on one of my clients prestashop following error occurs:

"(1/1) FatalThrowableError

Undefined constant "_PS_THEME_MOBILE_DIR_"

in Context.php line 292"

 

We don't know, how to solve this. Any ideas for this problem?

 

While log in to the admin of this page, we got following error:

"(1/1) FatalErrorException

Compile Error: Declaration of Doctrine\DBAL\Driver\PDOConnection::query() must be compatible with PDO::query(string $query, ?int $fetchMode = null, mixed ...$fetchModeArgs): PDOStatement|false

in PDOConnection.php line 70"

 

The current php version is 7.4

 

Thanks for all your help.
