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

Been there! The 406 not acceptable error often pops up when the server and client can’t agree on content types.

Quick things to try:
- Clear your browser cache (sounds dumb but works sometimes).
- Check if mod_negotiation’s enabled (Apache peeps).
- Test with a simple curl request: curl -H "Accept: */*" [your-url].

If it’s WordPress, a plugin might be messing with headers.
