theme.css 包含不允许的控制字符、注释或转义

Error message

theme.css 包含不允许的控制字符、注释或转义

What it means

Character guard in parse_safe_css: the stylesheet contains a character rejected by forbidden_css_character (control characters), CSS comments (/* */), or backslash escapes. The Safe CSS subset is deliberately comment- and escape-free so the compiled output is fully predictable.
