If you have troubles since the update to WordPress 4.5 please read this post before opening a new thread.
I have an established site in development that has been working, but today lost the connection to the database or something. While I can see the admin screen and screens for each formatted page and post, when I try to view the page, I get an error message that the file cannot be found on the server, plus a 404 error.
How can I re-establish the connection? Or is that the problem? What other information can I provide that would be helpful?
the front page appears fine, it is just when I clickthough to go to a constructed page or post, I get the errors mentioned earlier. It affects all pages, including those accessed by the header menus.
Also have the same problem when I create a new page from scratch. When I hit View Page, I get the server error.
please check your permalink settings (especially the structure). Go to Settings > Permalinks to view/edit/save the permalink structure.
Hurrah! That was the problem. Changed back to default and all the pages reappeared. THANK YOU!
