I had the same thing and I disabled a plugin which rectified that.
However, in my system status I have this:
Secure connection (HTTPS): ? ?Your store is not using HTTPS. Learn more about HTTPS and SSL Certificates.
Hide errors from visitors ? ?Error messages should not be shown to visitors
I have no knowledge of code and do not know how to edit files. I saw the post on GitHub but I don’t understand it.
Sad times all round ??
