I think the address should be text so that it can be more easily copy'n pasted...
Main page keeps vanishing?
Possible solution:
http://wiki.protospace.ca/new/index.php?action=purge
Cleared the cache, seems to have fixed it? - Nope, still happening. Needs more looking into, even this discussion page disappeared!
If the issue persists:
Remove === from end of page? Only the main page seems to be affected.
We're running 1.25.3 so this shouldn't be an issue (1.22.1 and above seems to have fixed this?).
Check log for PHP errors?
Raise PHP memory limit?
