[login to view URL] I have some minor problems with my magento store that need to be fixed. they are listed below: 1- The 'My wishlist' + login page won't load (top right) 2- On the social media icons in the footer twitter uses a Facebook icon, and i want to add instagram 3-When i enable the newsletter popup, it doesn't pop up, it just shows at the bottom of the page. 4-The search bar and the logo in the header are in each other places. I want the logo on the left and the search bar in the middle.
