sidebar is under content due to woocommerce

Hi, after installation of woocommerce plugin my right sidebar fell to the bottom of the page. I tried adding .container .clear {clear: none;} to my custom css but it did not help. Please help me fix this. This is how it looks on the page http://gregicpromet.hr/gp.hr/kategorija-proizvoda/skolski-namjestaj/skolske-garniture/
