ERROR: Access level to Inix2PaymentModule::displayWarning()

[ietax]

Hi I have a big problem, I cannot access on module section of my BO.

 

Fatal error: Access level to Inix2Module::displayWarning() must be public (as in class ModuleCore)

 

I tried this solution

 

open InixModule.php and find:

 

protected function displayWarning($msg)

 

Change to

 

public function displayWarning($msg)

 

Even if I have succesfully modified the file the problem is still present.
 

During my attempt to install the Cash on Delivery module with TAX an error occurred and it is now impossible to access to modules from BO.
 

I delete the folder Inix2Module from FTP and when I try to open the module section from BO the folder Inix2Module is created anew and the error shows up.
 

Is it possible that this error is caused by the uncomplete installation of the module?
 

Thanks
