QuickCRM

I have purchased a Full version and users get an "Invalid or Expired trial code" error message

Make sure users upgrade app from App Store or Google Play to version 6.2 or higher.

I get an error message asking me to check permissions when opening the app

You should first have a look at your PHP/Apache error log for more details on the error. It is likely that permissions are not correct in your custom, cache and mobile folders, and default_permissions are not set correctly in config.php.

The owner of these folders and files must be the Apache User or be readable and writable by the Apache User. If that not the case, change the owner of these files and folders.

All files in custom, mobile, service/quickcrm and cache folders and subfolders should have the same permissions and owner as index.php in your CRM root folder. All folders in custom, mobile, service and cache folder and subfolders should have the same permissions and owner as the module folder.

Once you have solved the issue, you should update config.php so that the problem does not happen again next time you install a new version of the server module.

You should first make sure that the apache user and group are set in config.php (default_permissions user and group). You should have

'user' => 'Apache user', // for example 'www-data' in default Ubuntu configuration
'group' => 'Apache group', // for example 'www-data' in default Ubuntu configuration

If permissions of index.php are 775, you should define :

'dir_mode' => 509,
'file_mode' => 436,

If permissions of index.php are 755, you should define : 'dir_mode' => 493, 'file_mode' => 420,
