I'm having no luck at all in activating the gift voucher and coupon modules. Whenever I try I get an error message of:
Fatal error: Cannot redeclare class ot_coupon in /home/sites/site10/web/includes/modules/order_total/ot_coupon.php on line 15
It gives the same error for either module when installed singly. All the other parts seem to be working OK, I can create and edit vouchers and coupons in the admin page.
I found an earlier post about it but their problem was sorted by a re-install: I've spent 7 hours doing that now and I'm pretty sure there are no editing bugs! Can anyone suggest a fix? I don't even know where to start looking. Why is it saying it's a redeclare problem? Where else would it be declared?
Any help would be so much appreciated as this site is committed to going live Friday, CCGV or not!
Thanks in advance,
