Houzez issues rebuilding

Hi , rebuilding a site for a friend after he got a virus . And there are some issues i find trouble solving with houzez .
1. Search filter doesnt work .Like if i search It wont work but if i choose category does . Also map makes no sense there , should be if Minimum a Madrid map . And the results dont display properly .
2. Logo looks so small but if i make It bigger It lose quality ( i know i fixed this with support like a year ago but cant find how and he IS out of support now)
