Hi Jodi,
As others have said, you do have a lot of pages. However, they are mostly text pages which shouldn't be a problem for an application such as web plus - in fact the app file size is quite small when compared to some sites I've seen.
There are a few problems with misplaced and some overlapping objects, but this can be easily sorted before importing into X5. One way to avoid this type of problem would be to use a strict grid layout, or even a table layout to ensure everything stays in position.
I've also noticed that your home page slider is squeezing the images which doesn't look too good. You can overcome that problem by cropping and sizing your slider images before importing them into the slider application - basically, you need to crop them to the actual dimensions of the slider.
On you video page, you may like to consider using a video lightbox to display your you tube video links (you can see an example
HERE.) A video lightbox can make the page look a little more interesting and uses a surprisingly small amount of code.
One other thing I noticed is that some of the ads that get displayed are not always appropriate for a site such as yours (ladies online now-type ads!!!). It may be best to skip this type of advertising altogether (unless of course it earns you substantial revenue)
Anyway, those are my thoughts, for what they're worth, but I see no real reason why the site shouldn't open in X5, there is nothing too adverse to prevent it from opening.
Kind regards
Frank B.
