Hi, Cory.
I’ve been experiencing the same issue at bluehost.com with one of my clients’ sites. The response I received back from bluehost was:
We have added nginx on the server (level of caching). You should either find a plugin that will do this without stopping the nginx or upgrade to VPS/dedicated level of hosting.
My client has shared hosting and upgrading is, unfortunately, not an option at this time. Any ideas for a way around this?
Thank you,
Al
