I have the issue that under “Appearance” menu I don’t have the “Theme Options” sub-menu and can’t edit any of the options described on the BizGrowth Documentation.
The BizGrowth is a free WordPress theme which is build in WordPress customizer where as the PRO theme is build in more user friendly Theme Options.
If you are using BizGrowth free theme, you won’t find the ‘Theme Options’ in Appearance.
Kindly go to Appearance -> Customize to setting the theme.
