I am trying to add WPMU Dev Dashboard on a new website, and I keep getting the following message:
Your server had a problem connecting to WPMU DEV: "HTTP Error: 403 "Forbidden"". Please try again.
If this problem continues, please contact your host with this error message and ask:
"Is php on my server properly configured to be able to contact https://premium.wpmudev.org/api/dashboard/v1/ with a POST HTTP request via fsockopen or CURL?"
I have checked with the server admin - he says there shouldn't be anything on the server site blocking/stopping this connection.
What else can I do to troubleshoot this issue? Server IP (just in case there is a block of some sort): 188.8.131.52
