I have been getting a lot of mail lately about people not being able to login to access the calculators, my apologies for the problems you’ve been having first of all. The short of it is, I don’t know what the problem is. I’ve been troubleshooting it for a couple months now and I’ve pretty much given up trying to find a fix.
A Temporary Workaround
The only thing I have found that seems to work sometimes to resolve the issue for some users is deleting the browser cache (delete cookies, temp files, etc.). Again, this has only worked sometimes so take that for what it’s worth.
The Plan Going Forward
I have started totally re-writing the code for the calculators. The idea here is to get rid of the login requirements all together. Obviously, this will take some time, I hope to have the first release done in a couple weeks. You’ll notice when that happens, the layout of the entire site will change.
Stay safe and wash your hands,
