Follow the below steps to add the trustmark to your OpenCart 2 or 3 site.
- When you download the McAfee SECURE app from OpenCart it will save as a zip file, you will need to upload this to your store.
- In the OpenCart dashboard navigate to the extension installer (it should look like a puzzle piece) and upload the zip file.
- Once done, you can click on the modify extension button to be linked to the mcafeesecure.com portal, where you can make an account and/or add your website if they haven't already.
- You should now see the floating trustmark on your website!
If the trustmark fails to appear in 3.x, try clearing the store caches (using the blue gear icon in the top right of the main OpenCart admin page). If McAfee SECURE doesn't appear on the layout edit page, try going into admin settings and making sure all administrator user permissions are checked.
