My site has a strange bug that came out of nowhere.
Single posts are just not loading. The page seems to time out half way through creating the categories menu. The menu loads fine on the home, archive, search and 404 pages. It is just the single posts that won't load.
The site was working perfectly and then this error started happening. I haven't changed anything.
I uploaded a fresh copy of the gallery and thematic themes to rule out any customizations I'd done but the problem persists.
Other themes work and load the single posts without any problems.
Any suggestions will be welcome and help greatly appreciated.
