Hello,
I don't accept your referral to e-dimensionz but would rather have you support the Canada Posts plug in that Hikashop sold me.
Hikashop did not sold you the e-dimensionz Canada Post shipping plugin but we in fact provide for free a Canada Post plugin.
If you or the e-dimensionz team can show us that the problem is coming from Hikashop instead of their plugin, with precise information of what is wrong where, then we'll fix that issue on our end, but
we can't fix issues from extensions that someone else is selling with support included, especially since we have a free equivalent which doesn't have the problem...
When we test it with our Free Canada Post plugin, it's actually working fine, so we can't exactly reproduce your issue. We don't even have the e-dimensionz plugin on our end, so even if we wanted to help you solve a problem for something you purchased elsewhere, we wouldn't be able to.
