Magento 2.1.0 CE, Bug Fixes and Upgrade - See Project Description for Bug Details

Magento 2.1.0 CE, Bug Fixes and Upgrade Hello, Please read this carefully before bidding.. Below is a list on bugs we need fixed before we can go live with our website, Wettattoo.com. We will consider this job complete once a test order goes through completely. Web Setup Wizard – We would like to upgrade to the current version of 2.1.3 CE Component Manager - Does not load, it just spins System Update – When doing a Readiness Check, we get the following error and cannot proceed “Check Component Dependency We found conflicting component dependencies. Hide detail Command "update" failed: Loading composer repositories with package information Updating dependencies (including require-dev) Your requirements could not be resolved to an installable set of packages. Problem 1- The requested package mirasvit/module-feed could not be found in any version, there may be a typo in the package name. Potential causes:- A typo in the package name- The package is not available in a stable-enough version according to your minimum-stability setting see <[login to view URL]> for more details. Order Processing ( I believe they are all related) Any test order is currently not going through and comes in as “Pending”. When we go to change the status we get a “500” Error Also both Front End and Back end checkout just timeouts and give “ Something went wrong” error message. We recently had a Plug-in by Signifyd installed which is not working. The plug-in is a Fraud Prevention. So an order when placed goes to our Processor [login to view URL] and then to Signifyd which approves or disproves the order. This is broken. Once we installed the plug-in the orders stopped going to [login to view URL] We are using a one page checkout plugin also which was working before. Our Server Admin has provided the following log message. [18-Jan-2017 19:18:50 UTC] PHP Fatal error: Class 'Signifyd\Core\SignifydAPI' not found in /chroot/home/wettatto/[login to view URL] on line 11 In addition within the Signyfd application, is uses “Webhook” to communicate with the Signifyd Servers. When we Test we get the following Error “Your server returned an error response code (500) for the test webhook Post”
