Consistently get "Yikes Something went wrong" with "My Portfolio" website

I faced this intermittently earlier but have been facing it far more frequently now that it is annoying.

Steps I do when I face this:

1. Go to https://seekingalpha.com/account/portfolio/all/holdings
2. Click on the share count in the "Shares" column for any of the stock ticker there. This gives the "Yikes Something went wrong" page.
   

Note that in step 2, instead of a ticker for which I already had a lot, I click on another ticker's stock, i.e. it's "Add Lot" button, it generally works. But if I click on a share count number for a ticker for which I already have a lot, it bugs out. Previous to the bug, it used to give a mini-drop down with add/edit/delete lot.
