Anyway to fix it ? ??

the 403 means *something* (a security solution) blocks PHP files in wp-content/cache from being executed/ accessed. re-enable “serve as static files” on AO’s main settings page and you should be OK ??

Thanks for reply.

I checked for a while, but did not found “serve as static files”.

Do you mean JS, CSS, or Misc Options part?

May you share a screenshot?

the first one under “misc options”;

Save aggregated script/css as static files?
