I am sorry to hear this is happening. Can you help with some additional information? What browser are you working in when this happens? Are you just seeing a spinning wheel or any error messages? If possible, please test in another browser on the same computer to see if the page will load there. I tested it out in Chrome on my computer and the contacts page loaded right away.
I am using Internet Explorer, it's the same browser I've always used with this site. I do not get an error message, I just get a spinning wheel that keeps spinning until I am logged out for being idle. It appears that all other aspects of the site are working for me.
Thanks for the reply.Do you know what version of IE you are working in?
Since it was working in the past, please try launching in safe mode.
Try working in this window to see if the page loads.
Were you able to load your browser in safe mode that @Hannah_M gave steps to above? Are you able to test on another browser? What version of Internet Explorer are you using?
I am using Chrome and I can open your contacts without difficulty.
Please try that and let us know how that goes.
