Greetings,

I have a daily SQL report monitoring 404's and 403's on our webserver. I noticed suddenly that one specific UBB gallery thumbnail file appears to have gone MIA as it is generating many 404's from a variety of UBB URL's.

I checked through the UBB control panel looking for a way to force rebuild thumbnails and found none.

Given the path of the MIA thumbnail, how may I rebuild it? It's relative path on our server is:
/ubb/gallery/54/thumbs/1109.jpg

I am thankful,
Michael
