Project Description:
This job is only available for the next few hours as we are waiting on our developer. If you can fix this quickly, then please bid.

This should be a fairly simple fix for someone skilled in Magento. We just need a developer to teamviewer into my machine and investigate issue and fix. The problem is that Post Affiliate Pro was not fully removed properly and is causing an issue. Here is a portion of the admin error message:

There has been an error processing your request
