vDATA - [Blank Page] after verification

Hello,
1. I just installed vData on a Joomla 2.5.8 website
2. I can see the vData menu in back-end
3. I selected the dashboard item from the menu
4. I've been asked to verify my account with email/password
5. Click on "sumbit" button and I got a blank screen

Now I'm trying to access every item from the vData menu but I see a blank screen on every click
If I go back to www.mysite/administrator/ everything seems ok but vData menu items don't work properly

Can you help me please?

Additional Info

PHP Version 5.6.32
curl enabled

Hi David,
It is built for Joomla 3.x, can be installed on Joomla 3.x websites only. However, you can still export/import data on Joomla 2.5 website. For more information Please follow this thread: www.wdmtech.com/forum/vdata/923-vdata-installation-issue#3951

Thanks Daniel
