Read this article. https://www.a2hosting.com/kb/developer-corner/php/using-php.ini-directives/php-allow-url-fopen-directive It shows you what you need to do. You will need ftp access to your files. You may need an IT person or developer to do it. Not sure your background.
I had this issue and resolved it. It worked fine on my dev site but not on my stage server so I had to compare and figure out what was set differently. I looked around and saw that you and other people had this issue, yet no one else has responded with answers. Anyways… try this and see if it resolves.
Check and make sure that “allow_url_fopen” is enabled on your server.
