I'm on a Nginx VPS server and after I installed the simple:press plugin on my site, it was working fine, until all pages on my website (not the posts) started to resolve in 404 pages. Then I updated permalinks and everything was fine again. Now, from time to time I have to update the permalinks because it went back to 404s.
I couldn't find anything related to that matter around, would you know what might be causing this? Thanks
