DB Error connecting, packets too big

Hi champs
My Fluent SMTP Is causing a DB Error connecting to database.
With cpanel.net saying its a wordpress issue, not cpanel core.
So i disabled all plugins one by one, and Fluent SMTP is the culprit.
Anyone can fix Fluent SMTP? DO i contact them directly?

Here are the errors:
