Fix several bugs that have risen from moving our existing PHP+MySql web application from Bluehost shared hosting to Amazon AWS. All code is in place, just needs fixing. These bugs are mostly JavaScript related

We are looking for someone to fix several bugs on our existing web application. The code is already in place and was all working when the application was previously hosted on Bluehost. These bugs only started occurring after moving the application to Amazon AWS, so it shouldn't require a tremendous amount of work to get it working again. The majority of the bugs are related to JavaScript/AJAX, so this work will require strong knowledge of JavaScript, AJAX, PHP, MySql, and Amazon AWS. Please message me for more details on exactly what the bugs are. If the freelancer does good work, there will be opportunity for future work. Thanks for bidding!
