do you have index.php as part of your link?
I’m guessing you’re on a windows server like me so go to this help page: http://codex.wordpress.org/Using_Permalinks and do a search for IIS 6.
Fixed:
Open notepad, paste:
cgi.fix_pathinfo = 1
cgi.force_redirect = 0
save as php.ini in main dir
its on the permalinks page about midway down.
Looking more at it, and it seems the links to the pages are being added onto the index.php link… so its http://www.page.com/index.php/about
… i’m so confused.
I’m having this problem too. Reloads to index in default mode, otherwise all post and page links become broken with a std “the page cannot be found error.”
Newly created pages don’t work either.
