Hello, I have a problem with adding a picture in the frontend editor using the addon "Person". Whenever I add an image and save, the page returns the error "page not found". Only going to the backend, hiding the addon or deleting the image and adding it again brings the page back. This problem occurs in a few addons, but not ball of them. What might be the problem?

Im using the newest pagebuilder Pagebuilder 3.81. with the Appliko Flex template, Joomla 3.10.5. and PHP 7.4. Thanks a lot for your help.
