I've set up my website home page as a static page. The posts page was working fine until I recently went through and edited some of the permalinks. Now only the individual posts can be read-- the blog page shows a 404 error.
I looked at a couple of support pages but was unsure of how to proceed. I've been using WordPress for a couple of months but I don't have much html experience, other than the occasional cutting and pasting of code. If I do need to modify the code, please be as specific as possible. Thank you!
