Start & End Sale Date

Hi,

No, the plugin available on this thread won't work on Joomla 4 and Joomla 5 as it is almost 10 years old.

However, since then, we've created a marketplace and offer an up to date version of that same plugin for free on this page of the marketplace:
www.hikashop.com/marketplace/product/222...-product-plugin.html
The version available there will work on Joomla 4 and 5.
