Q: How to reset all counts to zero?
A: You must totally uninstall JoomlaStats
1) Uninstall JoomlaStats database (this remove all statistics):
go to: Joomla CMS backend -> Menu -> JoomlaStats -> Tools -> Uninstall -> click Uninstall icon
2) Uninstall com_joomlastats in standard Joomla CMS way:
go to: Joomla CMS backend -> Menu-> Installers -> Components -> uninstall JoomlaStats component
3) Install com_joomlastats in standard Joomla CMS way:
go to: Joomla CMS backend -> Menu-> Installers -> Install -> choose com_joomlastats_v3.x.x.zip and install it
We sorry about inconvienence with uninstall/upgrade process but Joomla CMS does not contain upgrade option.
