Thanks for your response Mr. Vekia.
I mean i instal PrestaShop to my website http://eshopee.meximas.com, created using http://hostinger.in.
And when i go to manage my PrestaShop store website, when i login to my PrestaShop control panel, then there is nothing to do.
I mean there is no any way to add products, store logo, store details etc.
And at the bottom of my PrestaShop control panel showing Demo Mode On/Off note.
But i unable to off the demo mode.
I unable to do anything.
Please help me Mr. Vekia.
