I believe the errors are from your own computer. I have no idea how to fix that. As for the popups, they will no longer be there on September 1st as proboards announced this a couple of weeks ago.
And I only created this since a lot of members were complaining about the the requests in mod forum and that I had a spare board to share and also adventureran had web space to share as well.
So far it's working very well. There are now less requests in the mod forum and more utility news. And we, the graphics dudes, finaly have a place where we can just post our logos/graphics all over the place without caring what anyone would think.
try seartch the proboard support forum for help on your errors:
