Cannot link account

Hello Everyone, I installed and activated the plugin successfully. I am now at the page “Set up your Zendesk Chat Account” where I am supposed to link up my Zendesk Chat account. Problem: I enter my Zendesk username, password and also the subdomain (“syfe”). Once I click on “Link Up” it shows me the following error message: “Could not log in to Zendesk Chat. Please check your login details.”. The same happens if I keep the subdomain empty. If I change the subdomain to “syfe.zendesk.com” it forwards me to the next page without an error message BUT the chat want show up on my WordPress blog (I cleared the cache etc). Also the “Launch Dashboard” button would redirect me to “syfe.zendesk.com.zendesk.com” which tells me that the subdomain field only expects the subomain without the top-level domain. Shouldn’t be relevant but I am using the full Zendesk suit, currently still within the 30 days trial period. I appreciate your help! Thanks, Sebastian The page I need help with: [ log in to see the link] Ok this apparently is because we have Zendesk Chat Phase 4… Why is this not getting resolved??? igual me sucede a mi amigo a que se debera ese error ?
