Hey there, no worries whatsoever about asking this type of stuff, just so you know.
To see errors, do the following:
In Firefox, go to Tools->Error Console
In Chrome, click the wrench icon and go to Tools->Javascript Console
In both cases, unfortunately, it's not going to tell you what module on your site is causing the issue, but will tell you if you disable it (the error will be gone). I can tell you that it's likely a feature of your template, because if you open the HTML of your page (Chrome: Wrench->Tools->View Source) and search for "BoxHeights", directly above that, you'll see the inclusion of the Javascript file /templates/hot_sportal/js/equal_heights.js, which is coming from your template directory.. so if there's anything in your template configuration regarding heights of boxes, modules, menu's, etc, try disabling or changing that, and it may help.
Finally, try turning Error Reporting to "Maximum". This may do nothing, or it may spit out a lot of Warnings, and Notices onto your page in ugly text. If you see those (and it's only a few) feel free to copy them here, and it may help diagnose some things. If it's a ton, let me know, and we can figure out another way to see them. Once done, make sure you set it back to System Default (or None) which is how it should be configured for normal operation.
Hope this all helps!
