base href causing this

Hello, I have a spip website host at hostforlife.eu. I copied everything over and the site seems to be "working" with all the databases. The problem is I think there is a base href set. The stylesheet in the header was linked like this :

and was not working as it was going to the root instead of the website folder.

However changing the link to this (without the forward slash) works perfectly.

The problem is I have tons of links on the site that are all acting like this. Is there anywhere I can look to see what is causing this ? I can’t find a base href set anywhere and the htaccess file seems to have no effect.
