I am absolutley stuck. I have created several portfolio items and a page. When I click on the page in the menu it takes me to the page I have created, however If i click on any of the portfolio items I just end up at a 404 page not found.
Can't send you the URL because it is behind a coming soon page.
-Disable any plugins just for testing (Your coming soon plugin can remain as that shouldn't be causing the problem) -Try changing your permalinks back to default (Or custom permalinks if you are still using defaults). Only do this one time as it can cause a heavy load on your server. -Make sure you have cached the 404 error. Try another browser.
It should be relatively easy to sort out. Let me know if none of those easy fixes work.
