problem with theme Consulting WP by stylemixthemes

  1. The theme does not work in the basic functionality, writes the error [an error occurred while processing the directive] https://prnt.sc/v3ng78
  2. The loading of the site takes a very long time, about 10 seconds.
    For my request support stylemixthemes not answer a long time about 5 days,
    I ask the administration or give me a refund or the developers to fix all the mistakes, because I don’t need such a bad topic, if the client waits 10 seconds to get to the site, I will lose all buyers
