Hi  there!

  Does anyone is getting "CONNECTION ERROR"  in Boonex default iPhone App? 

Please can you specify the site you are trying to connect to ?

The problem is that /xmlrpc/ folder on your website generates an error. Please fix this error and mobile app should start working.

 Could you help me to fix it?  I have no clue what it is and how to fix it.
 Thank you in advance for the support

Thank you very much for your support and attention.  I guess you went sleep, but I figured out how to fix it.

Cause:  
Global_registers is ON.   Must be "Off"

Resolution:
I have to put php.ini inside this folder, since just one php.ini in root does not work in my case.

  In case you (users) is having the same problem of "Connection Error" and is reading this post.

- Open your browser and > Go to:  your_site/xmlrpc  
- if the page shows that Register_Globals is ON then place a php.ini inside this folder.

Note.  A copy of php.ini is attached here
