Recently there seems to be a lot of pics which aren't displaying, but showing as "attachment abxyz". When clicked on, there's a message that says "Invalid Attachment specified. If you followed a valid link, please notify the administrator".
Getting these on posts from experienced members as well as new ones.
E.g. http://www.buildyourownguitar.com.au...l=1#post178638
Any reason we know for this?
