Why would this be happening? Every link I click on on my site results in the homepage again. You can check it out here: http://www.whatamidoingonline.com
What is going on here? This just started all of a sudden this morning. I have tried deactivating all plugins (changing plugin directory name), tried publishing new posts and pages, etc..
The problem was caused by a plugin that was supposed to fix a permalink problem, so I deactivated the plugin and the old problem still persisted. Go to my site and click on any of the blog posts, you’ll see they result in a 404 error. When I first saw this, I tried yout method. I changed the permalink structure and they worked! but changing them back broke them again. I can’t change the permalink structure permanently because of link building and social media stuff I have already done.
I have seen this before. It was caused by a permalink saving error, in my case.
Go to Settings >> Permalinks.
Select a different permalink option than the one you’re currently using. Click “Save Changes”
Select the permalink structure you want to use. Click “Save Changes”
That fixed it when I encountered the same situation.
When your adding a new page, in the settings of the page when your editing it – under ‘Template’ make sure you change it from default to page(no seperators). This Worked for me.
