    Hi there!

    I am experiencing an issue with a website where I am regenerating a lot of thumbnails and I get the Error 500 from regenerate thumbnails UI. In the server error log I found a lot of errors of this type:

    Hi Francesco,

    Thanks for reaching out!

    The error message you’re seeing — “Got a packet bigger than ‘max_allowed_packet’ bytes” — is probably related to a MySQL server setting on your hosting environment. Specifically, it means that the data being sent to the database exceeds the current limit set by your server for a single query.

    This issue is not caused by our plugin, but rather by a server configuration that restricts how much data can be processed at once.

    We recommend contacting your hosting provider and asking them to increase the max_allowed_packet value in the MySQL configuration.

    Let us know if you need anything else — we’re happy to help!

    Best regards,
