Thank you for looking into this. Please find the answers to your questions below.
when you activate any of the Upfront themes (Spirit, Scribe or Fixer) there's an Internal Server Error and you're unable to access your dashboard, no matter if all the plugins are active or disabled. Am I correct? - YES, in fact I removed the domain from my server, added it again, and then installed everything one by one, however the issue persisted.
