[Plugin: Visual Form Builder] Theme layout is messed up after plugin update

Hello,

I’m quite new to WordPress and I’m building a website using the Twenty Eleven theme.

I have Visual Form Builder and Social Media Tabs installed, and everything’s been working perfectly, until today.
Since I updated Visual Form Builder from 2.4.1 to 2.5, the Social Media Tabs display is all messed up. I configured Social Media Tabs to use the slider on the left side of my website, but instead it shows up in my sidebars with an oddly small width.

The weird thing is that on the form’s page, the Social Media Tabs slider works just fine. When I switch to another theme, such as Twenty Ten, it works on all pages. I already looked on the internet, but couldn’t find the same problem. I think it might be something with jQuery though. I tried deactivating Visual Form Builder, but it doesn’t help.

Can anyone help me please?
