I look at the documentation link for theme update it says:
1. Update Theme through Admin Area
Updating your theme through the WordPress admin area is also the easiest way to update.
When you’re in your admin area, you will see indicators that something needs to be updated. If you click on those indicators, you will see which themes or plugins need updating.
In order to update your Theme4Press theme, simply check the box beside it, and click the “Update Themes” button.
(***Important: Make sure you have already entered your Theme4Press credentials mentioned before.)
However, it’s telling me my theme is up to date, even though I have version 2.7 installed. Please advise. Thanks!
