I'm getting this error on the post-new page:

Warning: require_once(/includes/functions_misc.php) [function.require-once]: failed to open stream: No such file or directory in /home/site/public_html/blog/wp-content/plugins/vbbridge.php on line 466

Fatal error: require_once() [function.require]: Failed opening required '/includes/functions_misc.php' (include_path='.:/usr/lib/php:/usr/local/lib/php') in /home/site/public_html/blog/wp-content/plugins/vbbridge.php on line 466

I would imagine that has something to do with the Forum Relative Path. My forums are in the main directory. I've tried several different things, including nothing at all.. What am I doing wrong?

Look at the third thing in the Limitations section of the main post in this thread.

Ah, I didn't even see that.

I tried it, and now it seems like the posts are posting to the forum, but still showing the error.

Where you see:

$vwd = getcwd();

Do as per the instructions in the limitations section (add the path):

$vwd = getcwd('/some/path/to/vb');

The images that are included in a comment, like smilies, images/comment_arr.gif and the images/buttons/viewpost.gif are not displaying. It is because they are referencing the images relatively. Is there a way to set the references to be absolute?

Sure, you could.. In the template look for something along the lines of:

Just use the absolute path there..

That works, but only for the comment_arr.gif. There are other images included in this line of code
whose image references are relative. Is there a way to set those images?

That is just the page text, not an image.

Take a look at this post on jeff's recipes. Look at it in IE so you can see the images not being displayed.

The last comment has 2 missing images: 1 for the comment_arr.gif and another for the smiley. It is the smiley that I would like to show.

Probably won't work because the way Vbulletin is coded to show the relative path. You can turn smileys off by changing the last argument to false:

do_parse($reply->pagetext, false, false)
