I had installed and tested the plugin on a staging\/test site\u2014using 5 paintings\u2014and everything was working fine.
Now I wanted to install it on the production site as well. However, it indicates that I have already activated 5 products and need to upgrade. I don’t want to do that for the time being.
So, I\u2019d rather remove the 5 paintings from the test site (which is a subdomain of the production site) and run the setup on the production site instead.
But… <\/p>\n\n\n\n

    \n
  1. The plugin no longer appears in the plugin list on either website.<\/strong> <\/li>\n\n\n\n
  2. However, “ArtinAR” still shows up in the settings on both sites<\/strong>. <\/li>\n\n\n\n
  3. When I go to https:\/\/artinar.app\/admin<\/a>, I get a page displaying the information below (which I have copied here as Markdown).<\/li>\n<\/ol>\n\n\n\n

    Error – Internal Server Error<\/p>\n\n\n\n
