Taking a quick look, here are some issues I saw:
Code:
Content visible to verified customers only.
In your header, you have a misformed td tag. You also have a meta tag in the body of your html.
Then, you have this:
Code:
Content visible to verified customers only.
Which is setting a padding of 25 pixels on your inner content for the page. You are using fixed width tables on PhotoPost, so you are getting middle content that is at least 925 pixels wide.
You can either reduce your PhotoPost width to 850 or use 100%.
PhotoPost is fitting inside your wrapper - when your wrapper sets the conditions for PhotoPost, then there isn't anything we can do within PhotoPost to compensate for that.
Keep in mind, PhotoPost is a seperate application and integrates with vBulletin; it does not require vBulletin to run, nor is it a "plug in" for vBulletin that uses vBulletin code. PhotoPost can run independently or with over a dozen other forums and while we make our best effort to work right out of the box with as amny configurations as possible; that doesn't mean that those with custom setups won't have to some tweaking.
