Thread: How many categories can be assigned to custom fields?

How many categories can be assigned to custom fields?

I'm struggling with custom fields for 3 days. I have 1100 categories and subcategories and I want to asign 10 new custom fields to all categories.

First custom field is assigned, but when I try to assign the second field, after update it isn't show up at all in admin.

It's very frustrating and I don't know what to do. I tried with fewer categories and it's working fine, but my client wants all 1100 categories.

The solution would be to implement these custom fields in php files or in function.php, but I have no clue where I can declare these fields so that can be written in the database. Or maybe is a hook that assign all custom fields to all categories from function.php.

I need badly an answer. Thank you.
