a lot of warning when i clic on the column name !

I tried this solution and I'm still getting the following:

Warning: mysql_real_escape_string() [function.mysql-real-escape-string]: Access denied for user 'ccrelics'@'localhost' (using password: NO) in /home/ccrelics/public_html/components/com_grid/GridBuilder.php on line 117

etc etc etc…

I'm using Grid version 1.5.8 on Joomla! version 1.5.26.

Any suggestions on how to fix this?

Thank you.
