My site has 4 plan levels for frontend submission.
Each plan level is connected to a specific user role.
I want to limit their submission while they submit a post through the MB Frontend submission, if they already posted their limit quota to show them a custom message instead of the form.
Let say we have a user with the role of "Start-Up" which is obviously a start-up business owner, the limit will be 1 company, 1 service, 1 portfolio and 1 job vacancy... which are the 4 CPT I have on my website.
Therefore, how can I limit this submission?
