You are having problem with database. Reasons are as follows:

1. You do not have permission to certain table/action
2. Once of the tables is corrupt, you need to REPAIR it.

Open up phpMyAdmin, select the database, click the checkbox on that table (jos_content). Scroll down to the bottom of the page, and in the select box select "Repair" that should solve your problem
