Don’t paste, even though I’m not sure what you mean by that in this context. It will not help. If a plugin doesn’t work as expected, or harms other software, this is something you have to have to bring to the plugin author and may be get an update. In the mean time, don’t use that specific plugin.
Lesson: Like when having big trouble with an OS, like Windows, first try to restart it, then uninstall the latest installed program. When having trouble with your WordPress installation, which almost always is a mix of core WordPress, a theme and bunch of plugins from different authors, first deactivate all plugins at any cost in labour, set permalinks to default, then switch to default theme. In nine out of ten (guessed) serious situations the problem then disappears and you can start a quiet investigation under conditions where the most important things actually work and you are in control (log in, view site). When the cause is clearly identified down to package level, and authors informed, the problem is almost already, or practically, solved.
And when informing a plugin author about a problem, or asking for help in a forum, always include your WP version, PHP version, theme, permalink settings and eventually what active plugin the problem seems to interfere with.
