Getting a 406 Not Acceptable Error – What’s Causing It and How Do I Fix It? or Why Am I Seeing a 406

OP here—wow, thanks for all the replies! 🙌

Tried the curl -H "Accept: */*" trick, and it worked! Looks like my server was super picky about headers.

Now I’m digging into why the Accept header got messed up in the first place. Maybe a recent plugin update?

Anyway, you all saved my butt. Gonna check mod_security next just in case.

Cheers! 🍻
