I have visited the Permalinks page and our permalinks are set to Post Name. I clicked submit to save the setting again, however we are still getting the 404 error message. Under Sermons, on the admin side, when I click on Topics I get an error stating “Invalid Taxonomy”. Once I click on this item, none of the other Sermons menu items work either. For example Sermons > Sermons now says “Invalid Post Type”.
Were you going to provide a link to the development version for me to try?
Thanks,
Doug
