match feed category

Match feed categories:

When a feed provides categories for a post, try to match those categories locally with Categories.

Unmatched categories:

When syndicated posts have categories on the feed that don’t have any local matches yet Create new Categories to match them.

This is not working.

I have lot of categories but no one of the feed post is not assigning to their corresponding auto created categories.

Please give any solution for this.

Thanks in advance.
