there are only warnings, not errors. These messages should never be visible on a productive and public website because a hacker can provoke such kind of messages and hack your website. Those kind of messages are only for developers and should be hidden by default. I’m not sure if you have access to the PHP settings of your server, if yes, you can turn off “PHP errors and warnings”. If not, please send us a mail to info @ 7theme . net, there is another solution to hide these messages.
