My posts are stacking on top of each other on the second place

I think it’s because of the thumbnail.

I’ve already saw this bug in my blog. Two solutions :

set a thumbnail to each posts.
set a min-height in your stylesheet for the stylish-popular-widget element.

.stylish-popular-widget {
     min-height:120px;
}

This solution isn’t really good but it works. Report the bug and maybe it will be fixed in th enext release. ??

The height thing didnt work at all

My popular posts are stacking on top of each other on the second place..

as Zenoble mentioned, this issue rises when your posts have no post thumbnails. In order to resolve the issue, you can just set a featured photo for those posts.

The height thing didnt work at all

Zenoble’s solution should work fine if you don’t want to use post thumbnail, I see that you are using cloudflare service which means when you modify a css file you need to purge the cache manually in order to see the changes.

I will make sure this issue is resolved when releasing the new version

Sur, that’s why i said that my solution “isn’t a good fix”, but temporary before the next version. ??

Set a min-height allows the .stylish-popular-widget element to keep a good height height even if there is no thumbnail.
