Unfortuantely, I don't have root access to my servr or db, I'm using a third party provider. Here' swhat I'm seeing every time I try to post a comment.

"user error: Access denied for user: 'changefo_dbuser@localhost' to database 'changefo_drupal'
query: LOCK TABLES sequences WRITE in /home/changefo/public_html/includes/database.mysql.inc on line 90.

warning: Cannot modify header information - headers already sent by (output started at /home/changefo/public_html/includes/common.inc:63) in /home/changefo/public_html/includes/common.inc on line 481."

The first part (the LOCK TABLES error) I get occaisionally with other operations as well. Is this something that means I'm pretty much hosed if I don't have root access to things to fix this?

thanks
