Pyrocms Pro: Fatal error with "Module_import.php" on site creation

[angiechan]

Using Pyrocms Pro. Creating a new site in the multi-site manager throws fatal error:

PHP Fatal error:  Call to a member function info() on a non-object in /www/pyrocms/system/cms/modules/sites/libraries/module_import.php on line 33, referer: http://mysite.local.domain.com/sites/create

I have some non-core modules in my addons folder. Before I had these modules, the site creation worked fine. Now that I have some modules, I get the fatal error. I tracked it down and it looks like the problem might be here:

system/cms/modules/sites/library/Module_import.php:149

Existing:
$this->install($slug, true);
Should probably be:
$this->install($slug, $is_core);

PHP Stack trace:, referer: http://mysite.local.domain.com/sites/create

PHP   7. Module_import->install() /vagrant/www/cms-core/system/cms/modules/sites/libraries/module_import.php:151, 

Anyways, I changed it and site creation now works for me.

Where did you put your custom modules? Chances are they are flagging as core erroneously or they are in the system/cms/addons folder.
