[Plugin: Google Positioner] “MySQL server has gone away” error message

Hi;

I’m using WP Google SEO Positioner (“Position Me” plug-in) on several of my sites and it’s working just fine.
However on one of my WP blogs I get the following error message:

WordPress database error: [MySQL server has gone away]
INSERT INTO wp_py_jobs_data (job_id, keyword, position, type, match_url, result_url) VALUES (, ‘K?ln Rodenkirchen Freizeit’, 1, ‘own’, ‘https://gaidaphotos.com/blog’, ‘https://gaidaphotos.com/blog/category/koeln-rodenkirchen/koeln-rodenkirchen-freizeit/’)

I disabled all other plug-ins and continue to get this error message.

Any clue anybody?

“Position Me” is working fine on:

It is producing error messages on:
