[Forum] Error when upgrading to 4.0.2

[Flexsim]

I get the following errors when I upgrade my software. How do I fix the problems?

Warning: fetch_template() calls should be replaced by the vB_Template class. Template name: downloads_navbar_button in [path]/includes/functions.php on line 3934

Warning: array_merge() [function.array-merge]: Argument #1 is not an array in [path]/includes/class_bootstrap.php(1146) : eval()'d code on line 4

You need to disable ALL plugins prior to upgrading from 3.x to 4.x.

Now that I have done it how do I get back to disable them?

Edit config.php and add this line right under <?php

define('DISABLE_HOOKS', true);

Thank you! That solve the problem!

Edit config.php and add this line right under <?php

define('DISABLE_HOOKS', true); 

But then disappear the blog and the home page

You need to remove your custom plugins that are not part of the software, or upgrade them to be compatable.
