What are the best troubleshooting steps for something like this?

Hello Ace,

do you have CRRs related to showimage.php defined in vbseocp?
Can you check your access log at the same moment to find out which URL gives this error?

Here's what I have, CRR-wise for that file:

'showimage\.php\?i=(\d+)&noignore=0&postid=(\d+)$' => 'image$1-$2'
'showimage\.php\?i=(\d+)&original=1.*$' => 'image$1-big'
'showimage\.php\?i=(\d+).*$' => 'image$1'
'/photos/index\.php$' => '/photos/'

Given that the gallery is now vBSEO'ed, I can't even remember what that one is for.

Ahh, temporarily commenting them out.. they are the links to the individual image pages by the looks of things:

PHP Code:

http://www.nzboards.com/photos/showimage.php?i=157 


That becomes New Zealand Boards - New Zealand Photo Gallery - Nature does wonderful things with no problems.

There are also errors for the journal..similar to the above ones. vBSEO-related?

*edit* Could this have anything to do with a need to use the rewritebase in my .htaccess?

Ok, thanks. What about the entry in access log (including referrer info if there is any) ? Probably there is a wrong URL in place.
