I have a post type (rgom) with custom fields (also called rgom). When I'm adding fields and groups to the custom fields screen everything is great until I get to 10 items. Once I hit 10, new items won't save.
WP 6.6.2
MB 5.10.2
MB AIO 1.30.2
Bricks 1.10.3
I have tried resetting permalinks.
I have tried rolling back MB and MB AIO to the last major version revision.
I have tried disabling every other plugin
I have changed from Bricks to Twenty TwentyFour
Always the same issue. If I delete a group (so there are only 9 in the custom fields) then I can duplicate a group, rename the group and fields and save and it works. Then if I try to add anything else so there would be 11 items, it fails. I mean, it says it saves, but the new field isn't there.
I have tried on my live web server as well as the same site on my local dev environment (Mac, Herd, DBNgin).
The live website has custom field groups with 50+ items and has always worked great. Not sure when it started puking. I haven't had to add anything new in a while.
