Unable to return to PRO version

Hello,

Three months ago I had PRO version for two months and, then, I changed the plan with “FREE” plan. Now I want to go back at “PRO” version. To do that I press on "Upgrade" button (from the right corner of the page) then a pop-up appear and I press on the button “Upgrade now”, a new pop-up with loading mode is appearing and then it is closing and nothing happen after this moment.

I checked the logs from Chrome Console (DevTools) and I have the following error:

Already another checkout is in progress
Failed to load resource: the server responded with a status of 500 ()

Can anyone to help me with this error?

Thank you and have a grate day,
Răzvan
