title: Sitecore Hidden Items
body: <p>Every morning when i try to login in my local sitecore login page, i almost have to wait for 5-6 minutes. When i opened the sitecore log files, i found bunch of debug lines similar to this "ManagedPoolThread #8 07:51:29 DEBUG Could not find a language mapping for source language id '{3C5919DF-1131-4B94-A96D-685C432CA586}' - skipping". The weird thing is when i search for that guid value, i can find the item however i don't see the item in the content tree by default. It's like the item is there but somehow it's hidden or content tree doesn't know the item exists. The guid value is for the language file, which i am not using in the project and can get rid of. Is there anyway to display all the items like this, which are there but hidden somehow from the content tree and delete them all?</p>
