* This block selects a random photo for display. It will only display photos
* from albums that are visible to the public. It will not display hidden
* photos.
*
* Once a day (or whatever you set CACHE_EXPIRED to) we scan all albums and
* create a cache file listing each public album and the number of photos it
* contains. For all subsequent attempts we use that cache file. This means
* that if you change your albums around it may take a day before this block
* starts (or stops) displaying them.
*
* If your Gallery is embedded and you call it via an URL,
* make sure you are giving the needed paramters.

Well, at first glance your Sidebar divs are not closed
<div class="bSideBar">
<div class="bSideItem" align="center">
<a href="http://www.scarchive.com/gallery/albums.php" title="My Gallery">My Gallery</a><br><br>
It seems like your include php just isn't working!!

Any ideas why?
Or some other code I can try?
Thanks

Sorry I can't help you with the problem you're having, but I did want to ask that when you post code please use the "code" button. As you can see, it makes the thread and code a bit easier to read. The "php" button does groovy color stuff, but I always use plain old "code".
Oh and yeah I'm the one who edited your post to use "code".

remove the red bit, it may or may not be enlightening ;)

EdB: Sorry, I will remember that.
Yabba: It was not enlightening unfortunately. No effect.
Is there anything my hosting provider could have done to cause this?
It's really hard to comment on your problem without a direct link and/or a sample of your random script.
