If you get a white screen when clicking on a page or trying to log in, here you will find a temporary workaround for this problem via inspect elements:
To open the inspect elements page you have to right-click any part of the webpage with the white screen and click Inspect. This will open the Inspect side-panel in your browser.
Alternatively, you can press Command+Option+i on your Mac or F12 on your Windows PC to do the same. Every modern web browser has a native tool for inspecting elements.
Click on the tab Application at the top panel.
(This tab can be hidden underneath the arrows).
Click on Storage at the left panel.
Click in the middle of the screen on the button "Clear site data".
You now have to log back in again and accept the cookies.
You are now able to view the page.
