how to ugrading to php 7.1

Hi Natureclean,

I created backup file , installed wamp server , then installed dolibarr (had to change the ports), Logged in to phpmyadmin and tried to restore the backup file-> but not working.

Are the ports same while installing dolibarr and wampserver ? Because while installing dolibarr, it was asked to change the port. So now i have dolibarr apache port as 81 and databse port as 3308.

Thanking you for the message.
