Error: You have exceeded the maximum allowed databases

You need to be talking to the Support folks at your web hosting company.

I could guess, but they’ll know for sure.

You need to be talking to the Support folks at your web hosting company.

Winner, Winner, CHicken Dinner.

You have a limitation on the number of db’s you can have and this is why you are getting the error.

This is actually easy to address but you need to work with your host.

It’s probably also a good idea to see if there are any old databases that are not being used that can be removed but you have to be careful not to remove something that is part of your live site.

I should mention that there is another possibility, which is why I directed the original poster to his hosting company: there are a few hosting companies that give that error message when you try to create a database on a web hosting package/account that has NO databases included in the “low end” package. i.e. – “the maximum allowed databases” number exactly Zero.

Do not forget that a single database can hold a great many blogs.

If you have a blog with wp-config.php like this:

define('DB_NAME', 'my-database');

/** MySQL database username */
define('DB_USER', 'my-username');

/** MySQL database password */
define('DB_PASSWORD', 'my-password');

/** MySQL hostname */
define('DB_HOST', 'localhost');

and that currently supports one blog then for the new blog make those details exactly the same but then scroll a bit further down that file to
$table_prefix = 'wp_';
and change that to
$table_prefix = 'wp2_';
and bingo – another blog in the same database.

Repeat as needed.
