ssl breaks wordpress css on tarotwikipedia

Hi, on my site, I have a ssl certificate, but i dont have https cause i dont take payments from people, however some pages open up with https from the contextual related posts plugin, and it seems to break the wordpress css. But it seems to mainly do this from the contact me site. Is there any way of making sure https dont load, and that i dont get any errors with https. Also, in case i wanted to use https in the future, how do i stop it from breaking my site’s css. Cheers, and thanks so much for all the help everyone is giving me :smiley: I really appreciate it.
