Installation and Update:
This extension supports OpenCart version 3.x, 4.x, cloud, events system, and the Journal Theme. No files are stored outside the extension, no files are overwritten and it does not use OCMODE/vQmode.
Each download file is the extension file to install. Download the ZIP file for the OpenCart version you require, use the built in installer, use upload button and choose that file.
If you have the free NaNet Extension Helper (v1.7 or later) installed, you can use export option (top right menu) within your extension before uninstalling. When you reinstall, the settings can be restored by using import option. This extension will also add an OpenCart header menu for easy access to all NaNet extensions.
