I've been trying to get on twitter for awhile now and i keep getting this error. twitter.com uses an invalid security certificate. The certificate is not trusted because the issuer certificate is unknown. The certificate is only valid for the following names: *.enflick.com, enflick.com (Error code: sec_error_unknown_issuer) Enflick.com is the creator of the online text app i use, TextNow. I don't why it says anything about enflick when It ry to get on twitter. My time is right and I cannot bypass the error by clicking I understand the risks.
