How to force a filter

Hello,
this is not related to the issue

- you get ALL results or you get ZERO results?
- what did enter for what type of field?

I have all results
My filter is set as 52## 1

Anyway i'd like to put some other filters to filter directly in sql statement with date/months

Could I make a plugin for that ?

Hello,
is the field allowed to be used as filter (=mark as filter for content lists)?

note: i do not mean to select it in component or category parameters as (visible) filter, i mean in the field configuration is it enabled to be able to used as filter?
... if not then it will be ignored

Yes it's set as filter. If not I could not try it as a standard filter.

Hello,
you can send me a PM with admin login for this
please include
- the ID of the menu item with the persistent filter

Hello,
you had not replaced the file
models/category.php
with the latest version that had given you

i guess you restored the original some time during testing and you forgot of it

it is working now
