Hi,
yesterday i've updated my old version of HikaShop Business 2.3.5 to the last version, because in the next days i will migrate my site to new Joomla 3.7.3 FINALLY !!!, but it's not a simple thing, and i think this migration take me some days.

In the old Joomla 1.5.26, every things works fine, execpt the product price modification. When i try to modify a product price whit the new system (the table with price and restriction) all works fine, on JS console non error appear, but when i click Save, Apply, or Cancel button nothing happen also in JS console.
The other functions and buttons in the page works fine but i can not save the modifications.

Many thanks and best regards
