Update

Step 1: Copy New Files

Extract the archive and copy the upload.../ folder (matching your OpenCart version) over the site's folder structure.

Step 2: Reinstall Modifications

For OpenCart 2.x and 3.x, you must reinstall the modifications (...ocmod.xml or ...ocmod.zip). Then, go to Extensions ⇒ Modifications and update them.

Step 3: Reactivate the Module

When upgrading to a new version, you may need to deactivate (uninstall) and immediately reactivate the module in Extensions ⇒ Modules. This will create additional database tables and new event handlers if required.

Step 4: Clear Cache

Don't forget to clear the store cache and browser cache.

Step 5: Reconfigure Settings

Re-edit and save the module settings.
