Blank Category Pages
If you clicked on one of your post categories and the page is blank, it's likely a plugin conflict. We usually see this error if you have two SEO plugins installed. When two plugins are installed on your site that are trying to perform the same function, it can cause unexpected results on your site (like blank category pages!)
- Go to your WordPress Dashboard > Plugins > Installed Plugins.
- Check to see if you have two SEO plugins installed (such as All in One SEO and Yoast).
- Deactivate one of the two plugins, and then check your category pages.
