I migrated from theme Mainroad to Stack and I love it.
However, I’ve noticed in my Google Analytics huge traffic drop and later on in Google Search Console a lot of 404 on my posts. Then I’ve noticed that in front of my base domain https://www.wojcieh.net all posts have /p/ in front of URL.
It is true that I had permalinks configured previously to
[permalinks]
post = "/:slug"
page = "/:slug"
but this setting is being ignored when using the new theme.
Include a link to the source code repository of your project, because we really need the context of seeing your templates and partials to be able to help you. It is trivial to do a quick git clone on your repo, then run hugo server in your project, to help you out. On the other hand, recreating your code from screenshots, or sort of guessing at it, is not.
If you can’t share your repository for whatever reason, consider creating a dummy repo that you can share, which reproduces the problem you’re experiencing.
