When I go with Firefox or Chrome to a RSS feed in the configuration pages (viewing the configured filters etc for any of my configured RSS feeds, for instance this page: http://192.168.1.5:8090/config/rss/?feed=BinSearch) then I get always the error message shown below. The page is initially frozen till after a few seconds the error message is shown. Clicking on Continue will lead again to a frozen page till the error message pops up again. After about 3 to 4 times clicking on Continue and waiting for the next error message, I can edit the page.
