i answer you already none will work 
the canvas page is against facebook policy's 
so you wont get facebook approval for the plugins to use facebook platform
and heaps other problems
and dont waste your time asking them to fix it as they will ask you to pay them to fix there plugins 

so basically you just throw 60$ away 
the sad thing is oxwall has known of there scam for over 3 years now and your just another in a long line that has been scammed by younet 

and dont believe there bullcrap when they say the plugins work fine on there test site 
so its your server or set up that problem and you have pay them to fix it 
as the scammers run different versions of there plugins on there test site that work 

and there set up instructions are wrong 
so no one can get them to work so every one get the same pay us to fix it answer 

I cant say I had the best experience with their plugins either. my advice is read the reviews before you purchase anything.

Dont trust reviews and rate as some dev have lots oxwall accounts and rate and review there own plugins

Use ratings to share your real experience with plugin/theme.
