 * I downloaded the iThemes plugin successfully, yet when I attempted to activate
   it, a fatal error page opened. fatal error: Call to undefined function wp()in
   xxx location on xxx line.
    I was able to return to admin page, yet any further
   action resulted in a fatal error page.
 * I cannot re-enter admin page using login.
 * This is not the first time with same plugin. Apparently, the con.fig was affected,
   according to my tech guy.
 * I was unable to delete from admin page, so I removed plugin from ftp.
 * Why is this occurring and what can I do to fix this on my end?
