Be careful!!! this plugin conflicts with many other extensions, even after it is uninstalled! I struggled hard to get back to the original status. Although it may be a good plugin, but there should be a warning like this, in case somebody may be misled by reviews below like me.
The jQuery library in Scriptegrator plugin can be conflicted with other jQuery based extension.
Of course in case you uninstalled this plugin, he is no longer active on your site. So I don't know what did you mean by "even after it is uninstalled".
