Hi there!

Sorry for the inconvenience.

Do you want to show the date in your given linked page?

Then you may use the following code:

.sp-simpleportfolio .sp-simpleportfolio-meta {
    display: block !important;
}

Note: Path towards custom CSS(Joomla 3): Extensions>Templates>Styles> Click on your current default template name then choose Template Options. Then find custom CSS within the custom code.

Best Regards
