Parse Error

I’m getting an error when I try to make changes and save a page. It is only happening for this one page. Any thoughts on how to fix the problem?

« MODx Parse Error »
MODx encountered the following error while attempting to parse the requested resource:
« Execution of a query to the database failed - Incorrect key file for table ’./joanne12_modx/modx_site_content.MYI’; try to repair it »
SQL: UPDATE `joanne12_modx`.`modx_site_content` SET introtext=’Three-time RITA nominee Joanne Rock turned a passion for writing into a career when imaginary characters kept her awake at night, demanding she tell their stories. A former Golden Heart recipient, Joanne has won numerous awards for her stories. Her work has been reprinted in twenty-four countries and translated into nineteen languages.’, content=’

Looks like a corrupted table. You need to repair it with your domain control panel database management system.
