No edit custom field option in our jira server

[Terry Tsang]

We are using Jira in our local server.
We notice that we are no longer got the edit custom field page when we click 
"Issue --> Field --> Custom Field" , only got "add custom field"

So that we could edit our custom fields now, e.g. add one more option in some pull down or delete unused field.

The problem is fixed.
The root cause due to the custom javascript hidden in one of the custom field.
so which cause corruption for it.

Hi, @Terry Tsang it looks like your intance has no any custom fields. 

You firstly shoud "add" them, then you will be able to "edit" them.

We had a lot "custom fields" , in the projects, field configuration scheme.
i can find in some where, but i cannot edit the option of it.

Try to reindex instance, it could help.

Your last screen looks like not out-of-box jira(apps).

i just got the image in "element id" --> Field
could find out the page of "edit", but i need to configuration the option

tried reindex still the same
