I reported this before and started moving articles with no categories to various categories. About 25% through that it started working. Then stopped again. I have now completed categorizing all of my articles. I cannot bring up the dashboard. I get the 2 screens when I try. See below.
Click the Dashboard button or right-click and open in new tab.
That means that there still a lot of articles - it just happened to be that you were at a time that not many people were online so it give you some additional resources - the moment there were more people the dashboard could not load once again - The issue/solution remains the same
There are no uncategorized articles. I have categorized them all.
