Cannot delete block.

Permalink
After clicking on delete block.
Normally I get a pop-up venster with Cancel or Delete.
On some site now I don't see the venster it seems to be out side the page.
How can I get to the venster.

Thanks for your help.

I believe that your problem is caused by a javascript/CSS conflict. Check your browser console for javascript errors. Check CSS assets. You must be 100% sure that there are no assets that loaded twice.
