If it happens when no plugins are active and wp default theme is activated, then it’s probably host issue.
Nothing weird, not the first author to have such deal with Envato.
I don’t see WP going anywhere in the near future, my opinion is go for it.
And as said previously, you don’t need that much time (well it depends on your free time you can dedicate to learning).
+1 for ASO (a smallorange), snatched their plan when they were giving 2x RAM for the same price, guys helped me set it up and it works with no issues since then.
There’s a $2 surcharge if one is not paying from his wallet.
The price you see ($4) is only for those who pay with money thats on their Envato account (either earned by publishing or deposited).
Go with 1140, that’s what Bootstrap uses and it’s just fine if you ask me.
Awesome @CodeFusion, thanks for sharing, did not know about it
