Piwigo 14.4.0 (Truechart on TrueNAS SCALE)

When I sync thousands of photos, the sync page errors to repeating this message over and over:

`Deprecated: addslashes(): Passing null to parameter #1 ($string) of type string is deprecated in /app/www/public/admin/include/functions_metadata.php on line 107`

Until it stops this this message:

`Fatal error: Maximum execution time of 30 seconds exceeded in /app/www/public/admin/include/functions_metadata.php on line 185`
