Fix
Install Time
If the error occurred during the TestLink install the most common cause of the error is invalid DB credentials supplied in the DB install screen. Check the MySQL root credentials, DB TestLink database credentials. Shared hosting would not have MySQL root access. We need to manually install the DB tables if that is the case.

During Page Access
If the error pops up while access the TestLink page or right after the login page then there is something wrong with the DB setup. Check if all the DB tables, views are properly installed, check the privileges of the TestLink DB user. Grant all privileges to the TestLink user on the Database objects
Check the logs directory for DB errors.
- audit.log
- testlink.log
- userlog<number>.log files.
Sample DB Example error:
ERROR ON exec_query() – database.class.php <br />1044 – Access denied for user ‘testlinkdb2’@’localhost’ to database ‘mysql’ – SELECT DISTINCT user AS user FROM user<br />THE MESSAGE : SELECT DISTINCT user AS user FROM user
Here this case the TestLink DB user has no privilege to execute the SQL query.
