Formatting on front page changed

I recently added and then removed a plug in to my wesbite, and, in so doing, messed up the formatting of the site. On the frontpage, the blocks of text should appear inbetween the image and the large white text, but right now that text is appearing underneath the image.

The site is https://www.recessart.org

Any idea how to go about getting that text back where it should go? Thanks for your help!

(I’ve been in touch with the person who wrote the plug in and he said that the plug in shouldn’t have affected formatting. So it must have been the way I installed or deinstalled the plug in.)
