I am using version 1.35 and experiencing the issue on 2 of my carts.
I have installed the following mod on both:
-Newsletter only subscription
I have checked the gv_mail.php code in the admin folder and it looks fine (no change from the original file)
Basically when I send a Gift Certificate Via email it will confirm all the field put in the form but when processed the recipient will receive the gist certificate without error but with a '0' amount not even the $ sign.
Same int eh GV queue or listing it list the sent GV with 0 in the amount column!!
I am now seriously stuck and need some guidance as to whether I should uninstall all contributions or else upgrading to the 1.37 version, will this help?
