After installing OC cant see products and cant log as admin

I have install new OC 1.5.6.1 and after installing I cant see products in home page. Also I can't log as admin.
i guess that problem is with path in config.php file but I'm not sure. My server provider has confirmed absolute path defined in DIR paths. Also I dont get any error in installing (steps 1-4) and I guess that Mysql is correctly configured.

Thanks for any help.

Hi Miloje,

I have accessed your live store. It seems your opencart system is failed to connect to your database correctly. Please confirm whether your database is running on your web server.

Please go to php.ini and find the following line code:
Then, replace it with:
Refresh your store again. The system should throw the detailed error message to you.

It would be better to let me access your ftp to debug the code for your current store. In this way, i could solve the issue for your store effectively.

Agree - looks like a DB connection error. Let us know how you go with Ocaddons instructions and what the error message says.
