You get the error message Unable to compile the theme "TcinnThemeWare...". parse error: failed at $...
Cause
Crucial here is the note "parse error: failed at $...". This means that a wrong value was entered in a configuration field and in which configuration field this is the case respectively the technical name of the field: $...
Example:
If the error message says Unable to compile the theme "TcinnThemeWareBath". parse error: failed at $sw-font-family-base: ‚Open Sans', sans-serif; (stdin) on line 11, at column 1, for example, the theme cannot be compiled or even saved due to an error in the $sw-font-family-base configuration field.
Note: If the error is not "parse error: failed at $..." but "Undefined variable $..." please have a look at this article:
Solution
Just change the corresponding configuration field.
If you don't know which configuration field you are dealing with, just visit the ThemeWare® Config Finder and search there for the technical name sw-font-family-base (without the "$").
After you have adjusted the field, the theme or the duplicate can be saved and compiled again.
If you could not solve the problem, simply start the ThemeWare® Debugging. You can open a support ticket in case you are not able to solve the problem yourself:
