Thread:Project:Support desk/Update previous MW 1.16.5 to 1.17.0 throws an 500 internal server error/reply (24)

I spoke too soon. The links are now back to their broken state, not sure what I did. Text is back on the Special:Version page, so that's good. It does not seem to be related to the browser cache. Still working on finding the 500 error log.

I also tried using a fresh copy of the languages directory from the 1.17 .tar download. But that didn't seem to change anything.

Update: I had made some customizations to the Vector skin, and copied that over to the new 1.17 installation. But I find that selecting the Vector skin that ships with 1.17 fixes the link problem. So will try re-implementing the customizations and see if that will do it.
