When a user creates a new link (colored red), and then goes to the link to create a new page and save it, then comes back to the original page, the link will still be red. It will be the shade of red of a visited empty link, but it will still show that the page does not exist. This lasts until a new link/page is created, or I 'touch' the LocalSettings.php file on the command line, at which point I can't find anything on Google like this.
The version of mediawiki for that site is 1.23.0, but I have another test site on the same server that is at 1.23.3. php version is 5.3.3.
I've updated extensions, etc. and still no change. Has anyone seen anything like this? Is there a maintenance script that will help? Thanks
