Resolution
Please consider updating the WP Toolkit extension:
If for any reason the extension update is not possible apply this workaround:
- Connect to the server via SSH
- Replace the
/usr/local/psa/admin/plib/modules/wp-toolkit/library/Db/Row/Instance.phpfile on the server with the one attached.
Note: For this workaround to work WP Toolkit version needs to be 6.2.9-7551 under Extensions > My Extensions > WP Toolkit.
