Some posts with a specific category won’t work

I tried to disabled the ‘W3 Total Cache’ plugin and it works. But the sidebar won’t appear for some categories.

Please help

How do you mean it doesn’t work?

Does the Category 2 archive not load at all when viewed on your site, does it load but not show the posts?

Have you tried creating Category 3 and moving the posts into this new category?

Also just to make sure, you should also try disabling all of your plugins 1-by-1 to see if a confliction is occuring.

We’re posting at the same time.

Have you double-checked that the widgets for your posts sidebar are in the correct sidebar?
