Hi Jean,
Thanks for using Super RSS Reader.
I’m not sure if the page is designed correctly as expected, but setting below CSS fixes the issue.
.et_pb_widget {
float: none !important;
}
You might have to try a different layout or try inserting different block or check with the theme author to see if there is acorrect way to fix this.
For now setting above code will work, but it is something not related to super rss reader.
Thanks,
Aakash
