My sidebar is on the bottom

Without a link – that’s tough.
It could be an image too large in a post. It could be posts done with Word or Office.
Could be bad code in the sidebar.
?????

Decrease the width of the sidebar in the style.css and see if that helps

@lucas:
That will not work unless he’s previously messed with the width. It will only cause further problems.

My site is: https://blogdelcucurucho.com and I use peaceful-rush-10 template.
Thanks for your help!

I think if you fix most of these it will help:

Click on a line number to see where the problem is in your template.
