Please start with version. Here that tells us which pp_standard.php you might have.

Is the currency unsupported by PayPal? If so, then you cannot make it be supported, by fiddling with the .php file or otherwise. However, you might have scrambled what you send. Along with Currency is not supported, you also have Security header is not valid, and refused because of an invalid argument. Those are not OC errors, they spring from PayPal. Read everything current in the way of instructions and code snippets that you can reach inside your PayPal account, follow what they say, and see whether that takes care of the security header and invalid argument. It is possible, for example, that you are sending the wrong designation for an otherwise valid currency (upper for lower case would often be a mistake, so follow PayPal's instructions and examples to the proverbial letter). If everything is right and the currency is still unsupported, then that's as far as you'll get with it.

Did anyone solve this.
