Unspecified errors Facebook and Google

Social login was working fine before and whilst doing some routine testing I noticed that Facebook and Google plus are giving an unspecified error #0.

Twitter was also giving an unspecified error #6. However, I fixed that with instructions found here:

Any ideas on the other two issues?

thanks
