# Recurring Single Post 404 errors

* [9 years, 8 months ago](https://wordpress.org/support/topic/recurring-single-post-404-errors/)
* I recently installed Yoast on my networks installation and network activated
it. Since then, I’ve been experiencing recurring 404 errors on my single blog
post pages on my main site. I thought it was just a permalink thing, and a few
times, I just refreshed the permalinks and things went back to normal.
* Today, when it happened, without refreshing permalinks, I started deactivating
plugins to see if I could relate one to the other. As soon as I deactivated Yoast,
my single post started working again without doing anything else.
* Has anyone ever experienced this before? I have a hard time believing it is directly
related to Yoast, but it’s the only conclusion I can come to. I’m guess it probably
has something to do with my htaccess file, so I’ll post that here too:

* Did you get anywhere with this? I’ve not got Yoast installed on this specific
site, but had the same problem. I worked out that it was because the first word
of the blog was the same as another page on the site with that word as permalink.
* As I didn’t want to change the permalink of the page, I just changed the address
of the post itself, not the title. And it worked.
* May not be the same issue for you though.

* No, unfortunately, I never found a solution. The client wasn’t using Yoast much
anyway, so I just ended up deactivating it and haven’t had the problem since.
