I found a solution to this at another thread:
If something is Wrong, it is usually due to the cache data stored in the browser.
You can force the browser to reload the page without using the previously saved data:
Here are the shortcuts for the respective browsers:
- Google Chrome
Press the following key combination when the page is open:
Shift + F5 - Firefox
Ctrl + Shift + R - Microsoft Edge
Ctrl + R - Opera
Shift + F5 - Safari
Ctrl + R
However, the current problem seems to work only if you delete all data from the cache.
How this works can be found here. Just select the currently used browser above.
