Thread:Project:Support desk/Server timeout when saving or previewing

Hi,

I have a new install of MediaWiki, as follows:

It seems to be installed correctly, but I get a timeout error whenever I try to preview or save page edits. I have checked my error log, and nothing is shown there, so I'm completely at a loss!

It is currently set up as a private wiki, but I can change this if it helps. Any advice is gratefully received.
