[galaxy-dev] Galaxy not updating usage history after data deletion

Hi there, I'm having an issue that I believe is commonplace amongst Galaxy users: that of the webserver failing to update deleted data promptly. I've tried using the Python script to force an update that was suggested somewhere on the Wiki, I believe, but to no avail. In terms of making sure everything is "deleted permanently" etc., I'm pretty sure I've done it properly. I'm using the "Main" server & it's been, perhaps, two weeks since I've permanently deleted the said data. Any help is appreciated! Many thanks, Eiseart
