Sorry it was in German
After correcting a link, the above error occurred.
I gradually switched off parts of the page and found out that it was due to the images.
I switched off all the images to test it more thoroughly. The page appears again. Then I put a simple image from ‘Add Elements’ into the column with the original image from Shoomshaper. And again the error message appears.
It seems to me that none of the images can be displayed any more.
So I can't get any further and would like to ask you to help me find the error.
I had also had a look at

but it doesn't help
