I have implemented your plugin on my website, and it's handling social login nicely. The only issue I am having here is this error after successful login:
Mixed Content: The page at 'https://remysreef.com/sub-categories/?subcat=ANGELFISH'
was loaded over HTTPS, but requested an insecure resource 'null://remysreef-exoticreefimports.api.oneall.com/socialize/redirect.html?provider_connection_token=fdea189b-5883-4f9e-8b62-10611dbc39bd'. This content should also be served over HTTPS.
I have researched the error, and found out in your file library.js, it handles redirect and sending provider_connection_token along with. Any ideas how to overcome this error?
