I’m using clouflare and a plugin called mashshare. When I activate it, screen 403 appears.
I contacted mashshare support and after several tests, they claim that the problem is related to cloudflare.
Where does this error appear, what is the domain and does it work if you pause Cloudflare?
You can pause Cloudflare from the Overview tab of the Cloudflare Dashboard, bottom right under Advanced Actions.
If the issue persists after Cloudflare has been paused, it means that there is an issue with your origin, Cloudflare is only operating as your DNS provider while it is paused.
