Error Activating Site Builder and Content problems

[DragoshW]

I've just upgraded from 5.1.6 to 5.1.7 and I can't use the Site Builder or the Quick Setup. Just the AdminCP works, I keep getting "Error activating SiteBuilder. Please try again." .
And I can't see anything of the content on the forum it says " That action could not be completed. Please try again, and if this occurs again please contact the system administrator and tell them how you got this message. " . What can I do ?? Please help !

Please, enable debug mode on your site. Follow these instructions.
1. Open your /config.php file and find the following line:

$config['debug'] = false;

2. Change this line to:

$config['debug'] = true;

3. Save the file and upload it to your server.
4. Open the /core/includes/config.php file and find the following line:

// $config['Misc']['debug'] = true;

5. Change it to:

$config['Misc']['debug'] = true;

6. Save and upload the file to your server.
Reload the page you had the error on.

I have done this and nothing happens, the page is the same.

When you click on a link that gives an error nothing else is shown? There isn't enough information provided to say what your issue is. You will need to open a support ticket and provide access to the AdminCP, FTP and the database. You can use the Submit Ticket link below.

I have opened a ticket . This is the only thing on the page : That action could not be completed. Please try again, and if this occurs again please contact the system administrator and tell them how you got this message.

This is the only thing on the page : That action could not be completed. Please try again, and if this occurs again please contact the system administrator and tell them how you got this message.

Then it means you haven't fully turned on debug mode. You have to edit 2 config files.
