Custom pages are causing errors with relative path references

[bzcomputers]

I have created custom pages in vb 4.2 that reside outside the /forum directory using this method:

[HOW TO - vB4] Create your own vBulletin page

The issue I'm having is that references to certain directories being called by vB are showing as relative and not the absolute path causing errors to be reported for the pages. Directories like:

/images/misc
/images/cms
/images/site_icons
/clientscript

Not only are the errors showing for the custom pages but also for my CMS which also resides outside the /forum subdirectory and is setup in the root of my domain.

All pages seem to display correctly but cPanel is reporting about 5 errors per page each time they are rendered. BBURL appears to be set correctly, but it seems the issue may be related to it.

Any help would be appreciated, thanks.
