You must have previously installed the "Newsletter Subscription" plugin and not fully removed it.

I don't think so, I do have another site that this option is functioning fine on.
The send mail has worked in the past and Ive made no changes since then

PHP says the constant "TABLE_SUBSCRIBERS" is not defined. Usually indicates a missing file (or a partially installed / removed plugin).

khitomer:

... PHP Fatal error: 1064:You have an error in your SQL syntax; ...
PHP says the SQL statement contains an error. Most likely because the constant "TABLE_SUBSCRIBERS" is not defined.

The most likely fix? Reinstall or Remove the plugin which added "TABLE_SUBSCRIBERS". One may also want to read this related thread.
