I've used various plugins and one of them I've deleted "forgot" an extra field in database.
I can't erase it!
When I "ask" PGC to erase it I receive the next message:
"This feature is still in production and will be realized in the next version".
This message appears in all versions of PGC but...
...none of them performs the cleaning.
I don't remember which plugin left the garbage in database but is related to comments notification.
The names of extra fields are:
comment_subscribe and comment_mail_notify
Can anyone solve this little problem?
