FAQ

Some providers of VServer blocks outgoing HTTP traffic, which is secured by HTTPS. This also block the activation requests of our modules.

A workaround:

The Workflow Designer included a way to force the downgrade to unsecured activation also if the Curl module is available.
To get this open the module Directory “modules/<modulename>/” and create a empty file “.HTTPLicense”.

Now the HTTPs Activation is disabled.

If this helps for your provider, you should consider to switch the Provider of your VServer. Even if they are very cheap you won’t get happy with a bad provider for a important system, like a CRM.

If you use a firewall to block outgoing traffic, please ensure the VtigerCRM system could connect to this IP/Port:

VtigerCRM6: 88.198.156.82, 88.198.156.83

VtigerCRM7: 178.33.34.114

Port 443 or, if not HTTPS Support is available, Port 80.

All of out Plugins use a complex system, to ensure that the saved license is valid.

Our developer had a lots of fun with the development of these check, because every new algorithm had to go through a test, within I would break these validation. This results in a secure way to validate the license after every Update, which allow us to eliminate the impact in your work.
These validations are necessary to keep the price as low as possible!

At the moment of License Validation there are several information, the plugins transmit to the license server over a SSL connection:

• The md5 Hash of your Hostname (Nobody could recover the complete hostname)
• Your License Key
• Your vtigerCRM Version
• Name / Version of Extension
• Filename and Filesize of the File, which runs the license validation

Nobody could rebuild any personal information from the stored data!

If there are any troubles with these checks or your license, most of the extensions works without changes. Only the administration of these extensions will be blocked.

If you wouldn’t agree with these validation, I’m sorry, but you couldn’t use my extensions.

Our modules are developed for the following server environment.
When your server differ from these settings, we cannot guarantee our modules will work directly.
Also we are not able to cover this with our free technical support for the modules. Please contact us for commercial support.

If you need to downgrade our modules, you don’t get a guarantee from our side, that is is working as expected.

We take care to make downgrading possible, but don’t especially test this in different environments.

How to downgrade?

This is as simple as a manuell update. Download ZIP file from our shop and upload them to your VtigerCRM directly within Module Manager.
Vtiger would call it “Update”, but you get the older version after the “Update” is finished.
