Hi

We're getting some traffic from facebook at the moment where facebook is requesting images when people include our site in their hyperlinks.

This traffic is not getting the images it expects in reply - see the log below.

 

Before I spend too much time trying to debug this.... does anyone have any ideas or suggestions what is going on?

Cheers

H

Hmm.... this seems simple enough - it seems to be a bug in the requesting URL - it contains HTML-escaped "&" characters - so that stops the module working... not sure how or whether to fix this - I'll see if I can find anywhere on facebook to log their bug... but I may also put in a small fix... any opinions?
