SuiteCRM installing New Modules Error

"Specified directory '' for zip file 'upload://upgrades/module/cert_of_insuranceA252016_06_17_033953.zip' extraction does not exist." including a log file error of "…[FATAL] ERROR: rmdir_recursive(): argument is not a file or a dir."

I created a few new modules for 1 Reason's insurance CRM (customer relationship management system), including one module to allow clients to create and print commercial insurance information online 24/7, but when I tried to upload the module, I received the above errors. 

There were two things that I did to correct the error:

I changed the permissions of many files, but I don't think that actually had an impact.

Then, I changed the config.php file in the following manner:

//  array (
// Changed 6/16/16 in attempt to fix the uploading of new modules problem
//    'dir_mode' => 1533,
//    'file_mode' => 493,
//    'user' => 'sitecrm',
//    'group' => 'sitecrm',
//    'chown' => 'sitecrm',
//    'chgrp' => 'sitecrm',
// 	),
array (
	 'dir_mode' => 1528,
   'file_mode' => 432,
    'user' => '',
    'group' => '',
   'chown' => 'sitecrm',
   'chgrp' => 'sitecrm',
 	),

As you can see, I changed the  dir_mode and file_mode, and removed the user and group variables. After making the config.php edits, the module uploader worked perfect.

SuiteCRM is a great open-source CRM solution
