Mobile Edition Addon Error

[Mehrpouyan]

Hello,

I Installed Mobile Edition Addon From This Help :

 

"Installation Instructions

 

Begin by downloading the Mobile Edition from the parent license key page in our client area @ http://www.whmcs.com/members/clientarea.php?action=products

Unzip the files to a folder locally on your computer

Create a subfolder on your WHMCS installation named "mobile"

Now upload the files into that folder

Next login to the regular WHMCS admin area and go to Help > Check for Updates to force an immediate update of your local license key

Now you'll be able to access the mobile version using your regular admin login details @ http://www.yourdomain.com/whmcs/mobile

 

That's the installation complete and ready to run!"

 

but i get this error on mobile version :

 

Fatal error: Cannot access private property WHMCS_License::$keydata in /home/username/public_html/client/mobile/index.php on line 0

 

i found this topic : http://forums.whmcs.com/showthread.php?73446-Problem-when-installing-Project-Management-add-on

 

i uploaded new admin files to my custom admin foler ( 5.2.7 admin files ).

 

Can You Fix Problem ?

Hi,

Please try uploading a fresh copy of the /includes directory.

 

If the issue persists after this, please open a support ticket with FTP and WHMCS admin access details so we can investigate.
