my cs cart version 4.11.2

https://forum.cs-cart.com/topic/46775-orders-email-sending-to-customer/

I tried this and change in fn.cart.php but nothing happen.

please provide solution

for example my store name is ABC.com and a vendors name is xyz,abcd etc. when customer placed order and received email notification stating sender name xyz (vendor) and email subject as well xyz.

Default;

XYZ : Order No. 654454

I would like to have similar

(store name) ABC : Order No. 654454

Same with email sender name ABC instead of XYZ.
