From a blog by Kids In Glass Houses on Myspace:

unfortunately for all involved, i can now confirm that the remaining paramore shows are CANCELLED. not postponed to a later date. i'm really sorry to all you guys who were looking forward to the shows and who'd paid out travel and accomodation costs on top of the ticket. we're as sad as anyone that we didn't get to finish the tour properly, but it's out of our hands so all we can do is wish paramore the very best and hope they get through their troubles and sort out whatever needs to be sorted. hopefully we'll get to play with them and NFG some time in the future because they were ridiculous amounts of fun to play with.

Thanks to dontyoufakeit for the heads up on this information.

We are very sorry to all of the people that have just been cancelled on. This is obviously a very hard time for the band, so keep them in your thoughts as they work through this.
