Joomla error - Unknown column 'client_id' in 'field list

This error can be thrown up following a Joomla update. We have experienced it a couple of times with different customers and each time, the following fix has worked for us:

You may be getting a white screen with no menu items in the backend of your site. If so, skip to 'method two' below. If you are able to access you administration area and all of the menus, follow these steps:

1. In the administration area go to 'Extensions' | 'Manage' | 'Database' | Fix'

2. Then go to 'Components' | 'Joomla Update' and 'Resinstall core files'

3. Run the database fix again.

This should clear up the error for you.

Method two

If you do not have access to the administration area menus, try running the database fix by entering the URL to directly access it. To do this, copy / paste the URL below into your browser but replace www.example.com with your web site's address

• http://www.example.com/administrator/index.php?option=com_installer&task=database.fix

Press enter and then the database fix tool should run and your database should be repaired, allowing you to access the administration area as normal.
