Hi Shayne,
at the first view of your post I'd say immediately: Check Your Forum Links! That means you should check your Settings within the ACP! Check...
- PhotoPlog Link
- BB Code Link
- PhotoPlog Full Path
- Upload Dir
Especially the Full Path is very important to get a proper working. Here's the way to get the needed info. In case you don't know it...
1. Create a file. Say "path.php"
2. Insert the following lines
Code:
Content visible to registered users only.
3. Now copy the file into your vB directory and enter for example:
"http://www.thechiefbaboon.com/path.php"
4. Now copy the whole path into the ACP field "PhotoPlog Full Path". That should help you
