Shipment method error in product view

[Cococoder]

Hi guys,

VirtueMart 3.2.10
Joomla! 3.8.3 Stable
PHP: 7.1.12

NOTE: same error with same config on PHP 7.0 on another site.


Effect: instead of the shipment method, a letter is displayed. It use to work fine. Link gives you a live example: https://store.seobytes.eu/index.php/en/product-variants/multi-variant-detail

Shipment methods display correctly in the cart page.

Trouble shooting steps taken so far:
Try with different template and clearing cache (no changes)
Try on two different sites (same issue)
Delete Shipment method and create new ones and clearing cache (no changes)

Any suggestion or help welcome.
