Got an inquiry from our client and Moriai @moriaiy and I can reproduce the problem.
Only newly registered users are unable to connect to the marketplace from their Concrete CMS site.
Steps to reproduce
- Sign up a ConcreteCMS.com user
- Login to your new Concrete CMS install. (Checked with v9.1.3)
- Go to “Extend Concrete” page
- Click “Create Project Page” button
- The attached unknown error happens.
Again, this ONLY happens to NEWLY registered user.
I’ve tried the same step with my user, and I was able to connect to the marketplace no problem.
