A Human When I attempted the install of enterprise_v6.15.1 - it stalled on an all white screen and now when i try to access acylmail I get the error - Call to undefined function mb_substr() Peace AH
jvstratum Hi, That's an outdated Acymailing version. Please download the latest 6.18.0 from your account (https://www.acymailing.com/account/license/) and try to install that one.
mihha To add to this. You will also need to install and enable PHP module called mbstring If you are not sure how to do it, please contact your server hosting support to do it for you
