You have changed the default values (Appearance) of a WordPress theme and now you would like to reset them to their original values ? Here's how to do it !
The bad solution
If you uninstall the theme and you re-install it, chances are: nothing changed !
The good solution
Indeed, most theme save their parameters in the
options table (which name might prefixed depending on your installation choices), in a serialised manner.
You only have to find the line with
option_name starting with
theme and ending the theme name, then delete this line. If you install the theme again, the original values are reset.
Happy theme fidling !
