After blank page [PrestaShopDatabaseException] Table 'ps_product_reductions' already exists

[eomer]

Hi there

 

I've edited E-mail settings, clicked Save button and that's it, I faced a blank page, both admin panel and shop. At first, I've changed _PS_MODE_DEV_ and display_errors values in defines.inc.php. Then, I saw error "Call to undefined method Db::getInstance() in /home/crewshop.com.tr/httpdocs/classes/shop/ShopUrl.php on line 159".

 

After that, I asked google and found somethings. According to those, in confic.inc.php, made the line " setlocale(LC_CTYPE, $locale.'.UTF-8', $locale.'.utf8'); " comment with // and didn't touch other 3 setlocal. Then I faced "PrestaShopDatabaseException" (the scrrenshot of the page is attached). How can I solve this problem, what should I do?
