I'm referring to https://forum.bitcoin.org/index.php?topic=19379.msg242484#msg242484
For me, I don't even get the PHP error. When I go to Extentions - Payments in OpenCart, I see the module but I cannot Edit it to enable it. When I click the edit button, I just get a blank screen without any error or notice.
I am an absolute OpenCart beginner, just installed it yesterday and I need only to accept Bitcoin payments. This is the first extension I installed. I performed steps 1-3 in the README of the extention with step 3 being a copy:
cp -r /var/tmp/tabsa-opencart-bitcoin-payment-module-96ebf79/upload/* /var/www
/var/www being my OpenCart directory. I use Debian. A strange thing that I noticed is the URL that the Edit button points to: http://10.32.87.184/admin/index.php?route=payment/btc_mybitcoin&token=7d8f1f1f762ae2debc71d3e2da8f927c
While in the post that I refer to, there is no mention of any token.
I'd be glad for any light shed on this.
