PHP expert need for Quick on site php code/function repair work

The max budget for this project is 35 USD. Please do not bid if you wish to go above that. This consist of 5 problem to be fixed. We believe a developer can fix these is 3 hours max. I will provide a general explanation here. 1. Our users, after login in as users are not recognised as users when they want tp perfor certain actions on site. 2. In the list of stores on our site, "N" is being added at the end of every name on a particular list. This is not the case in other areas where the store ´name appears on site. 3. Our product comparison matrix page is not appearing when user clicks on compare products. It use to appear as a new window. 4. A SORT_ORDER function was added but is no longer working. It controls in what order product appear on page. 5. Our product listing page has a grid section too. A function that was added to the listing page needs to be added to the grid section to control how shops names and logo appear. Depending on the developers profile and skills, we shall provide specific links to the developer to experience the problems on site to know if he/she can fix them quickly. A detailed file describing the problem and how they can be reduplicated on site will be provided to the possible winner of the project. Any developer that impresses us should count on an immediate new project from us.
