Fancybox Plugin – All Image Galleries now in one column

I have a problem with my image gallery, i went in changed the column number to 8 for one gallery page and then saved. Realised this broke the page and now all the images were displaying in one column. I then went to change this back to 5 columns but this didn’t fix the problem. Now all images in all galleries on the site are displaying in 1 column downn the left side of the page.I tried deactivating and uninstalling and reactivating and reinstalling fancybox, but this didn’t fix the problem. I think it may be a plugin conflict but not sure how to fix this. Any help greatly appreciated, Thanks!
