Upgrading/changes to current webside (PHP webside)

Website is [login to view URL] This is a ad website in Norway for transfer cars (Free rental cars, when car rental companies send their cars on one way rentals, they need to get that car back). They can then post their car on this website and find a driver who will drive it bcak for free. So this website has 2 kinds of users. Car companies and drivers who book these cars. We are doing some bug fixes, changes, upgrades. The project requires some testing as well. I got some bugs where I havent located the problem. Most things are functionalites, some few minor design changes (icons/text). You will be working on my development server and transfer to live after testing and my approval. I need everything to be perfect before transfer to live. I will not approve before I am 100% satisfied. I am looking for someone who is willing to do a better job than expected, and who are not here for doing an OK job just to get paid. I will from here on call them advetisers, drivers and users if it applice for both. Requirements: Bugs: 1. One of my buttons dont work on safari browser. Need to implement safari compability to this button. Should work on all browsers. Button is "Mer Info" on the booking page. 2. Some users get an error message when clicking the email confirmation link after registration of new user. Need to do testing and find out why and fix the problem. Users who get this error is also not registered in my databse for some reason? 3. Optimize input fields on registration form. For example: minimum requrirement for postal code in norway is four numbers. in current form users are able to add postal code with just three numbers. after registration the fields should clear and show the confrimation message. 4. when a advertiser change/update their current ad, they sometimes get logged out from their account. The change is confirmed, but they should not get logged out. I also want a confirmation message to appear after the change is submited. Language: 1. The page is currently in Norwegian language. I want to add a english language selection. So the users can swap between norwegian and english. I will provide the translation sheet. The language selection should be placed in the top header/nav bar. Advetiser: 1. When an advetiser get a booking for a car, they will receive an email to confirm or deny the booking (all bookings is on request only). I want to add confrimation message when the advertiser accept or deny a booking. currently they only get sent to a empty page. I will provide the confirmation/denial text. 2. If the advertiser has several booking requests on the same car and choose to accept one of them, the other bookings should automatically be denied (a denied email will be sent to the driver, this denial email is already made). Currently the advertiser has to deny all other bookings manually, otherwise these drivers will not get any feedback on their booking. 3. When an advertiser add an ad, the fields in the form must be cleared. Design: 1. I want to change some of the icons on the booking page. 2-4 icons. I will provide the new icons. others: 1. I want to add google analytics to the website. 2. On the front page there is a contact form where users can contact us directly. After submited the users currently dont get any confrimation, the page just relaods. I want to add a confrmation message that the query has been sent. I will provide the message. 3. I want to add social media icons/links on the website footer. I have added some drafts of some of the issues. I will add more when we discuss the project. Please ask if something is unclear.
