After a full system update I encounter an incompatibility issue between the TM Extra Options plugin and the Measurement Price Calculator plugin.
This is what happens:
When a product it set to an area of 1 (square meter for example), the price is displayed as ‘free’, as can be seen with this test-product: https://www.cavallo-floors.nl/winkel/parket-testproduct-measurementcalc/
When I set the area to 1.0000001, the price is displayed correctly again. (https://www.cavallo-floors.nl/winkel/eiken-den-bosch-geborsteld-wit-geolied/)
Also, when I deactivate the TM Extra Options plugin, the price is displayed correctly.
Somewhere, there seems to be some kind of issue with compatibility and handling of prices.
Could you look into this?
