Just Converted website from http://htmltowordpress.io

Hi, I just converted my website using http://htmltowordpress.io. They provide Simple Live Editor for editing of content. When I go to the edit page it throws error

wp-content/plugins/simple-live-editor/admin/class-simple-live-editor-admin.php(412) : eval()'d code on line 6

Can Somebody help how to resolve the problem?

Also, their support mail sends auto generated mail, so no use.

We do not provide support on the forums for errors in external code conversion tools, as they will take specialized knowledge to debug and resolve. Please hire a web developer.
