I just installed Magento 2.3 with sample data on an Ubuntu 18 VM.



I'm playing around with creating themes based on tutorials I found online. I created a sample theme, uploaded it, logged into admin, and then switched to it with no issues.



Now, I'm having an issue trying to switch to an alternative theme. For some reason, I can't seem to change themes anymore; even though I could before.



Here are the steps I go through:




  1. Log in to the admin panel

  2. Go to Menu -> Content -> Configuration

  3. Click 'Edit' under 'Action' column



What I now get is a page that looks like this:



HTTP Error 500



I don't recall doing anything noteworthy after I first switched themes from the default to the new one I created.



How can I fix this?



UPDATE



The URL reporting the 500 error is the following:




https://<my-magento-install-url>/admin/theme/design_config/edit/scope/stores/scope_id/1/key/<some-long-number>/
