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?
