I have created a view type content, with the follow features:
Format
Format: Unformatted list | Settings
Show: Content | Teaser
Fields
The selected style or row format does not utilize fields.
Filter criteria
Content: Type (= article)
Content: Published (Yes)
Sort criteria
Content: Post date (desc)
When I checked the option "Expose this sort to visitors, to allow them to change it " in Sort Criteria>Post Date and press Apply, the sort Expose doesn't show and when I am going again to Post Date I can see that the change was not stored, the "Expose this sort to visitors, to allow them to change it" appears unabled.
What's my error?
Thanks for your help.
