With all the IT issues that QF has, I'm not surprised. I used to get some weird errors on QF website, but most of them work on the second/third attempt ...
So, as an IT person, I'm inclined to ask ;
1. Have you tried closing all browser sessions and search again?
2. Have you tried a different browser ? Chrome, Safari, Firefox, didn't think I'd say this, Internet Explorer?
3. Have you tried using InCognito or InPrivate browsing modes?
4. How about clearing the browser history/cache ?
Some of the above have yielded positive results for me, however, it's not a solution
Finally, "Have you tried turning it off and on again"
(for those not in the know, this is a reference to IT Crowd sitcom)
