I cannot create new module instances. Neither save new ones nor create copies of existing ones. When I open an existing module instance and close it again without saving it, the lock is shown in the overview.
The following error message appears in the browser console:
Mixed Content: The page at 'https://www.braun-immowert.de/administrator/index.php?option=com_modules&view=module&layout=edit&id=579' was loaded over HTTPS, but requested an insecure stylesheet 'http://fonts.googleapis.com/css?family=Muli'. This request has been blocked; the content must be served over HTTPS.
In addition to that there is a second message, please see second screenshot.
Any idea how I can solve the problem?
Best regards
Thomas
