ASPX Website Hosting Transfer, Fix Configuration Issues. URGENT HIRING

Need an expert who can rectify the issues our client is having with their hosting transfer. All Files and Databases are moved over to the new host, but some "[login to view URL]" related issues are making the site unoperational. Error snapshot is attached. I need someone who really understand this issue and confident enough to fix the error. If you failed to fix any error, you will not get paid. So only serious bidders are welcome. And make sure you use any of the word that is quoted in this description inside the First Line of your proposal, to make sure you have really gone through this description. Thank you.
