What will I do to make my account active again?

I was trying to request for payment or transfer fund but an error message appeared that says"There’s an issue with your account"

I was inactive for a while but I need to use it now.

You need to contact customer services to resolve any limitation or account specific issues.
Click help / contact bottom left of Paypal pages for options available for your country.

Or have you considered contacting Customer Service via Facebook or Twitter?
You can send them a personal message from their Facebook or Twitter pages.
