I'd installed RC4 but in the kayako admin cp >> modules it says "1.0 RC1". Just see you got a newer version RC5. I tried to force upgrade in kayako admin cp >> modules, it has the same numbers. Problem #1 =========== kayako admin cp >> breincoach >> settings >> Plugin General Details 1/ have whmcs as slave try to log in and get "Plugin file not present or not readable: " 2/ have whmcs as master try to login and get "Invalid email or password" both users are already in kayako and whmcs. Questions ============ 1/ where do I upload the key? kayako root directory? 2/ in our current kayako v3 and whmcs we have users in both databases. but users login to whmcs to gave access to kayako and whmcs. will this plugin sync with existing users?
