update: now Page Attributes seem to be back on board – for some reason they were disabled in the Screen Options. Uff. Backup – and on we go… Thank you!!
oh wow! Thank You!! Deleting the json files made the “ghost” field group disappear. Now i only have the problem that i still can’t access the Page Attribute – probably because I checked “hide” with the problematic field group “gallery”. Do you have any suggestion how i can solve this issue?
Thank you!!
This of course didn’t really solve my problem of having editorial staff with different language browsers – but at least now I know what causes the problem.
I read that adding a language marker to the field could force the numbers’ format… like this:
<input type="number" lang="en">
Is there any way to add such a language marker to the number field?
Thank you very much!
I solved it – turned out the CPT was ‘corrupt’ and didn’t accept any news fields. On the backend everything looked ok, but i couldn’t get any data from whatever new field. So I added a new almost identical CPT, moved everything over and – voilà – it worked.
