Hi, Diego. Unfortunately, I’m not going to be much additional help. We never did find a solution. Along the way, the error stopped happening, however. The parameters are no longer on the page.
Either that stopped with a HubSpot wordpress plugin update or it may have resolved when we updated the software we were using for our support system (the login landing page). Maybe there’s a programming solution based on the way a login form is built, but that’s simply speculation and beyond my technical abilities.
Best of luck!
