I understand your frustration, Cecilia. I said:
That is the currently the case. I say currently because generally, the support staff currently are not capable to fix this issue and this needs further investigation that is why I have posted this in our issue tracker.
Regarding WPML compatibility, WPML is compatible with X and Cornerstone. Translation (including saving) works as I’ve personally checked other users’ sites with WPML.
What’s happening here is WPML extensions conflict. We surely would want all WPML extensions to work but because there are numerous extensions, it is not feasible to test each and every one for a variety of use cases. This is why I reported your case.
You said the Advanced Custom Fields Multilingual is causing the saving issue. Maybe you can disable just this one so you can use WPML String Translation?
I also missed to say that for this error: POST https://lightflow.waxandgold.com/de/cornerstone-endpoint/ 500
, please try contacting your host if they are blocking cornerstone-endpoint
usually from Mod Security. Please ask them to whitelist that directory.
Also try reinstalling WordPress by going to Dashboard > Updates and clicking the Re-install Now button.
I understand that you have a tight deadline but we would need your patience regarding this.
Thank you.
