Got an interesting one, right now using a translator service to increase my traffic as my site is popular in alternative countries, however, the service I use has a CDN themselves they serve from and update from the original page every few hours. When APO is off, everything works correctly.
The issue I seem to have is once this is properly cached on the other CDN side, APO serves white blank pages on the subdirectory translated pages using the cache of the other CDN, my normal site is fine like it’s always been with APO.
I’ve lowered TLS settings, checked re-writes, server resources and PHP isn’t an issue and I cannot use a cookie to disable their cache as it disables APO as well (How caching works in GTranslate network? | GTranslate Help Center)
Has anyone had any experience such as this? The service is gtranslate.io business edition with subdirectories.
