Hi I can’t seem to go into Courses or Certifications to complete my content marketing course. When I click on either it says:

Hey @Tmerwe just checked on a few different browsers and networks and this works fine for me. It would lead me to believe this is a local issue. Your network may be blocking this or it may be a caching issue. I’d try clearing your cache or try a different browser. If this doesn’t work it’s a network issue, which I wouldn’t be able to troubleshoot remotely tbh.
