1.) Rebuild the styles.
2.) If a child style template has already altered, then the modifications to the parent template will not propagate.
Now is a good time to backup!
Find out what templates are being modified by your 'mod' by looking at the '
productfile.xml' -- if the author does not list the templates modified. Using 'style Manager', check your child styles and if the template's name is in 'red', you will need to 'revert' it. (Note - You will loose any data that is already in the template, so make sure you have a backup of the style.)
