I have installed many themes on wordpress.  I have tried to install this theme on two different wordpress droplets on DigitalOcean.  Every time the theme installs successfully, but fails after installing the first plugin:
<h1 style=”font-weight: 400; color: #1d2327; font-size: 23px; margin: 0px; padding: 9px 0px 4px; line-height: 1.3; font-family: -apple-system, BlinkMacSystemFont, ‘Segoe UI’, Roboto, Oxygen-Sans, Ubuntu, Cantarell, ‘Helvetica Neue’, sans-serif; background-color: #f0f0f1;”>Installing Plugin: DawmThemes Core</h1>

Downloading installation package from https://xxxxxxxxxxxx.com/wp-content/themes/ticketbox/includes/plugins/dawnthemes.zip…

Unpacking the package…

Installing the plugin…

Plugin installed successfully.
