Earlier today a bug occured that refreshed the main feedback page whenever a user tried to search ideas or navigate from page 1 of ideas to any other page on all UserVoice feedback sites. When errors like that happen we say pagination (the process of dividing content into separate pages) broke. Additionally there was a brief period of time when trying to navigate to any idea produced a 404 message. While the 404 error only occured for a few minutes, all customers were affected by pagination issues on and off between the hours of 9am and noon PDT. The error was introduced accidentally as our deveoplers were fixing other bugs.
Thanks for bearing with us and we're happy to have gotten everything back in working order so quickly! As always, let us know if you're still having issues.
