There is two setting for advance features image setting, but i only able to save one ” Use advanced image finder”, “Verify featured Image” seem like some issue with my setup, everytime i check and click save it turn out uncheck again.
Advanced “Featured” Image Settings
Verify “Featured” Image
Advanced Setting. Uncheck only if you are 100% sure that your images are valid or if you have troubles with image verification.
Use advanced image finder
Check this if your images could be found only in the fully processed posts.
This feature could interfere with some plugins using post processing functions incorrectly. Your site could become messed up, have troubles displaying content or start giving you “ob_start() [ref.outcontrol]: Cannot use output buffering in output buffering display handlers” errors.
