ThemeRoller gets 500 errors in console when changing textures

[minusdavid]

Before realizing that themes came with a ThemeRoller view/modify link, I was trying to manually create a new theme based on an old theme.

And every time I tried to change the texture in Chrome on Windows 11, the ThemeRoller would change the theme in difficult to predict ways. When I look at the console, I see the following:

"Failed to load resource: the server responded with a status of 500 ()" parsetheme.css:1
