Thread:Project:Support desk/Mediawiki page link shows with brown colour (page doesnt exist) error and unable to save the page

I have nearly 1000 text pages and when i tried to add more pages. I saw the page is getting created and the link shown with brown colour. When i keep the cursor near to the link i saw it says "page doesn't exist". I saved it and not error is thrown but still the page as well all the subsequent pages shows in brown colour.

Is it a limitation in Mediawiki or there is a page limitation which we need to increase via configuration setting?

Thanks.
