I am using CiviCRM 4.6.7 installed on CMS WordPress version 4.3.1 and I'd like to install the extention CiviVolunteer. From Administer > System Settings > Extentions, I choose CiviVolunteer version 4.5-1.4.1 but the system shows me this error: "Sorry but we are not able to provide this at the moment. Multi-select is not valid option for field html_type
Can you help me?
