I was working with CQWP and after a while I had a lot of Content Query Web Parts on my masterpage, I deleted all and later found out that I couldnt see/access Content Query Web Parts under Content Rollup.
My Sharepoint server publishing service is already activated. Please what went wrong.
Edit: I just found out that I mistakenly deleted contentquery.webpart from web part gallery. How can I rectify this.
