Ok, i have tried to upload/overwrite all the files and overwrite the product. Now it's displaying as ICash 1.1.2 under Vbulletin Installed Products.
However, the negative amount donation problem still exists.
Any idea which part have i done wrong since TalkBolts mentioned that everything is working perfectly now?
I'm still getting "Successfully Donated 0 Points To nickname."
I do not dare to uninstall/remove everything and install again because i guess the points settings might be gone after doing that.
Please advise. Thank you.
