 * Well, in attempting to install plugin Calendar 3.0, I was instructed to put in
   a “patch” with lines of code for classes.php in wp-includes/
 * When I did, the site wouldn’t load and gave me a parse error on classes.php
 * So I deleted the calendar3.php file and entire Calendar 3.0 directory in plugins…
   still didn’t work. So then i uploaded the original classes.php (before the patch,
   which I had made a copy of), but then got a different parse error.
 * So then I downloaded classes.php from a different site that I had installed WP
   on and uploaded it to the trouble site and got a different line parse error.
 * Help! What can I do to get it back?

 * I thought the whole point of plug-ins was to negate the need to hack the core
   files?
 * At any rate, you may need to download a fresh-version and replace the core WP
   files. Have you contact the author the plug-in to see if he has any advice or
   have you checked the plug-in site to see if anyone is experiencing your issues?
 * Good luck,
    Michael.
