I need more details about the field that you are adding, what's in the field group you are adding to, and to what is it assigned, as well as details of the error itself.
Do you have details of the error from your logs?
The error occurs when you try to add the field, or when you try to save the field group after adding a field?
It might be easiest if I looked at your site to see details of the field group, so let me set up a private reply for you, but please share the errors from your logs if possible, and also, what kind of field are you trying to add to which group?
Hi, sorry for the delay, the problem appears when adding a field, no matters which type it has. I paste all the errors the log show when adding a Simple line field:
- mod_fcgid: stderr: #3 /var/www/clients/client3/web283/web/wp-content/plugins/types/application/mode in /var/www/clients/client3/web283/web/wp-content/plugins/types/vendor/toolset/toolset-common/inc/m2m/relationship/query/condition/type.php on line 28
