Price change on the declensions Fiche Article Front Office

[Ciiid]

Hello everyone,

 

I have a problem that has appeared on my site recently.

On my Back Office, on an item, I set him a base price.

I then created declensions (one not impacting the price, the other yes).

On the article sheet (on the Front Office), when I want to select the declination impacting the price, I have no price change that occurs (whereas if I add this declination to the basket, the good price is displayed) and I have an error in my browser console:

core.js: 1571 POST http://version.aupaysdessenteurs.com/en/home/206-13801-test.html?quantity_wanted=1 500 (Internal Server Error)

Can someone help me.
