Hi there,
I've installed and configured a little prestashop in local and have uploaded to a hosting. While I've been configuring furthermore in hosting, I got a strange error, that I think, it's only me got this problem. Because when I searched in google, I saw only my topic on this forum's another section about the problem and nothing else relevant to the problem. The strange problem is a database exception as "Table 'ps_product_reductions' already exists". I wrote the problem this forum and no one has answered.
the screenshot of the error:
Then I thoght that, altough I would lost some work, it's better to reupload. And I turned to my localhost. While I was making arrangements to move the site to another server, I got the same error in localhost. This made me really crazy! I was thinking that I was cursed, then I decided to delete db, and to create again and import the backup on both localhost and hosting. When I did this, The problem didn't solved in localhost, it's still there. However, I got even worse situation than previous: I can not connect new database by prestashop! The error I faced is "Link to database cannot be established: SQLSTATE[42000] [1049] Unknown database 'cshop'". However, I could connect phpmyadmin by using exactly same parameters. To be sure I wrote a quick php with mysqli_connection exactly the same parameters in settings.inc.php and uploaded to hosting. This php can connect with no problem.
I think I'm really cursed. Please somebody help me, and I need urgently.
