“Display filter on” not working

Hello,

Most likely this is a conflict with your other plugin or theme, as I cannot reproduce this problem on a test server.
Please try to deactivate all your plugins one by one and check the issue. Thus you will find out which plugin causes the error.
If it won’t help, try to switch temporarily to a standard WordPress theme.
Afterward, let us know about the result. This will help our developers to solve your problem faster.

Brief information on the main setting.
