Demo Installation failed - Only theme does not work fully

Hello support team,

i bought the Evolve theme and tried now two days to install it. I checked the "only theme" and the "demo" installation. First of all, the "only theme" work nearly perfect but e.g. the menu in the navigation does not work and I can't use shortcode in the "call us" block like you did in the demo. Although it shows icons when i put the Font-Awesome in the link box, it is alway vertical and does not work like in your demo. There are some smaller issues like problems with the portfolio items (hence, I'm missing some more information in the documentation). However I did nearly everything to get the "only theme" version working:

1. I copied profile/drupalexp_evolve/libraries to sites/all/libraries
2. I copied profile/drupalexp_evolve/modules/contrib to sites/all/module and enabled it in the module section
3. I copied profile/drupalexp_evolve/modules/drupalexp to sites/all/module and enabled it in the module section
4. Drupalexp and Evolve themes from profile/drupalexp_evolve/themes to sites/all/theme and set Evolve to default
 

If I understand everything correctly that is all I have to do. Well, I removed everything and wanted to try the demo version. I am able

1. to create the SQL query - the import works fine and creates the tables

2. copy the demo folder to my webspace

Hence, if I access my site www.domain.com/user I get always an error:

PDOException: SQLSTATE[28000] [1045] Access denied for user 'root'@'localhost' (using password: YES) in lock_may_be_available() (line 167 of /var/www/vhosts/domain.com/httpdocs/abc/includes/lock.inc).

The password and the user are 100% correct - I checked that twice.

What should I do?

Thanks
