No offence but from an administrator I was expecting a more intelligent answer. I already said what country I was from and blocking scripts shouldn't have an effect on the Paypal API and definitely wouldn't throw an error like that.
I figured out the problem, which I keep forgetting. I accidentally clicked Israel instead of Ireland when signing up on Paypal a while ago and never needed to change it up until now.
Sorry if I'm coming across as I dick, you can close this now if you'd like. I've emailed Paypal to change my country.
