I was successful in getting php5.3 back up. But I had to edit the php5.ini manually to add the right path to PEAR. I see the "include_path" pointing to the folder PEAR said it was installed to and that is reflected on the phpinfo page. But there is not a new "section" for PEAR. Should there be?
Just to confirm, I replace the menu.php.php file by deleting it and renaming the file you sent (PEAR_Mail_using_SMTP_php.php) to menu.php.php and placed it in the same folder (/webassist/email/).
Finally, can you check the attached waue_nominate_1.php page please? Dreamweaver says there is a syntax error with the line you asked me to add.
