I was able to change the txt on the individual product page from out of Stock to the txt I wanted (Sorry, This WYSIWYG Item is Sold) but I would also like this message on the main products page so customer dont wast time on out of stock items.
Here is an example of what I would like you will need to scroll down a line or to to see it.
please download and install a plugin named as woocommerce, activate it after installation.
you will then need to add a new page named as shop and set that page as the shop page from the woocommerce settings area.
you will be able to add products using the woocommerce plugin and those products will appear in the shop page.
you may also use full documentation of the woocommerce plugin, click here to check https://docs.woocommerce.com/documentation/plugins/woocommerce/getting-started/
