can't get results

hi there
I have logged into ritetag from when I joined authorised the app with Twitter through Tweetdeck and Sprout Social. However, today Sprout Social keeps asking me to log in and I do but it still won't accept that. With Tweetdeck I am logged in but when I click into a #hashtag word it will not give any results as it normally does.

Not sure why this happened today ...
thanks
Paula
