Successfully read database variables.

Error reading database variables.

Query executed: SHOW VARIABLES like 'version'

The "SHOW VARIABLES" query statement is required to obtain necessary information about the database and safely execute the installation process. There is not a single setting that will make this query work for all hosting providers. Please contact your hosting provider or server admin with this link and ask for them to provide support for the "SHOW VARIABLES" when called from PHP.
