Quick fix for 404 error in WordPress category / tag page
Just a quick fix for a common problem: Sometimes, especially after switching themes, wordpress will generate 404 errors on the category and tag pages. There might be multiple reasons – and also multiple solutions – to this, but I’m usually very successful with this:
Go to your WordPress backend, click Settings, click Permalinks. Make sure the category base is “category” and the tag base is “tag” (unless you have some VERY weird special settings) and simply press the “save changes” button. Even if nothing has changed, clicking the button will probably make your category and tag pages work again now.
Don’t forget to clear your WordPress cache for testing.
