I know there are two posts about this error on SO. Like every google result I found, the solution is : don’t work with Jailbroken devices. But mine is clean and my client’s one too.

I developed two apps with Paypal. The first works pretty good. The second shows the message DEVELOPER ERROR: FILE SYSTEM CHECK FAILED in debugger when Paypal button is initializing.

Of course, the same code (with same application ids) are declared in both apps.

An idea ?

    For all people like me, who

    • are using Paypal iPhone API since before august 2011
    • have migrated their mac on osX Lion
    • Now have this message during Paypal initialisation and after a new app compilation
    • … and does NOT have a Jailbroken device, of course

    Here is the solution :

    • Just download the new API version
    • change [Paypal getInstance] by [Paypal getPayPalInst] in your code (WHY did they change that ?…)
    • change

    this callback method

    - (void)paymentFailedWithCorrelationID:(NSString *)correlationID andErrorCode:(NSString *)errorCode andErrorMessage:(NSString *)errorMessage

    by

    - (void)paymentFailedWithCorrelationID:(NSString *)correlationID

    And your done.
