Fix OpenCart PayPal Checkout

My OpenCart store was recently updated and, since then, the PayPal checkout button is routing customers to a completely different payment processor.

Here’s what I need:
– Pinpoint whatever is overriding or hijacking the PayPal module (extension conflict, database flag, or template override).
– Restore the standard PayPal checkout experience so the correct gateway appears on both desktop and mobile.
– Run at least one live or sandbox transaction with me to confirm the fix.

You’ll be working with OpenCart, so familiarity with its extension architecture, vQmod/OCMod, and typical PayPal plugin pitfalls is important.
