I am having issues trying to setup Clickatell SMS provider, I am running Civi 4.6.26 on wordpress 4.7.5 using the clickatell extension 3.0 and have a Clickatell Platform account.
I keep getting "ERR: 001, Authentication failed" I am not sure why I have checked the username and password, and I can log into the Clickatell portal using those details.
I have tried putting in the "api_id=" in front of the api key but then it says it is invalid.
any help would be appreciated
