Note: You can check the current PHP version in your WHMCS. To do so, proceed to 'Utilities' → 'System' → 'PHP Info'.
3. Extract the package and upload its content into the main WHMCS directory.

The content of the package to upload should look like this.

UB2 2.png
4. When you install Unban Center For WHMCS for the first time, you have to rename the 'license_RENAME.php' file.

The file is located in 'modules/addons/unbanCenter/license_RENAME.php'. Rename it from 'license_RENAME.php' to 'license.php'.

UB2 3.png
5. In order to configure your license key, you have to edit the previously renamed 'license.php' file.

Enter your license key between the quotation marks as presented on the following screen. You can find your license key in our client area → 'My Products'.

6. In the next step, set up the 'storage' folder as recursively writable.

This folder is available at 'your_whmcs/modules/addons/unbanCenter/' .

UB2 4 2.png

Important: Make sure that the 'exec' function is not blocked in your PHP configuration.

Note: Once cron is executed, it operates continuously.
If you stop the cron processes manually, please delete the entire content of the '/yourWHMCS/modules/addons/unbanCenter/storage/crons/' folder or execute the command below:

rm -r /yourWHMCS/modules/addons/unbanCenter/storage/crons/*

Configuration and Management

Unban Center For WHMCS allows you to provide your clients with an ability to easily unban desired IP addresses from external servers.

Additionally, you are able to protect specific IP addresses from the unban action.

Unban Types

Our module has been designed in such a way so as to allow you to manage banned IP addresses on several different panels of a particular type.

These are:

  • cPanel - unban on CSF, cPHulk (Blacklist Management and History Reports) or Imunify360 (you may use one or more unban types at once)
  • DirectAdmin - unban on CSF, IPs blacklist (/usr/local/directadmin/data/admin/ip_blacklist) or both at once
  • InterWorx - unban on native firewall
  • Plesk - unban on Fail2Ban
  • You may also create your own submodules. To learn how to do that, please read carefully this section.

It is also possible to unban only the current IP address. You simply need to select such option (i.e. Allow User To Unban Current IP Address Only)
while setting the configuration or create a list of IP addresses that, no matter what type you have chosen, will not be unbanned (Blacklist of IP addresses).


In dashboard you can find the summary of currently enabled unban configuration for products, pending tasks, active services and last cron run.
The tasks list allows you to follow the current auto-unbans for the clients who log in to their WHMCS client area (the option may be enabled in products configuration).
These will be performed via cron.

Configuration of Products

Here we show you how you can easily enable and configure unban action for your selected products.

Let us show you how to enable unban functionality for cPanel Extended product.
First, go to the 'Products' section and press the 'Edit' button next to the chosen product.

UB2 11.png
Press 'Enable' and then define 'Minimum Delay Time' intervals to declare how often your client will be able to perform unban action on a specific product.

Next, enable the desired unban type/types. For cPanel there are:

  • CSF
  • cPHulk
  • Imunify360

Additionally, you can permit your clients to unban their current IP address as well as automatically unban them after they log in - Auto Unban After Login to client area (cron execution is required).
Note Auto unbanning feature does not work for dedicated/VPS servers type.

Select the email template that will be used to notify clients when their IP address has been automatically unbanned.
You may easily preview and edit the default, inbuilt with the module template content at 'Setup' → 'Email Templates', read more here.

You can also allow your clients to see all banned IP addresses' from the panel on their VPS/Dedicated Servers.
In case of Hosting Account, your clients may get an option to show the reason of ban before any attempt to unban the IP address.

Finally, by marking the 'Debug Mode' you will activate the extended logs in the WHMCS module log section.
Confirm those settings by pressing the 'Save Changes' button.

You can optionally add a custom hostname as well as add port number and select SSL connection.
Note: If you leave the hostname empty, the server details assigned to that product will be used instead.

Next, leave the default client's IP address to unban or provide a custom one.

Note: These connection details will appear only in case of dedicated/VPS products used by the client. For hosting accounts, only 'IP Address To Unban' field is available.

UB2 21.png

Creating 3rd Party Submodule

The main goal of Unban Center For WHMCS is to allow you to quickly and easily create additional submodules.

All you need is a little knowledge of PHP programming language and documentation of integrated module API.
Required information regarding the submodule itself is located inside the exemplary submodule.
It can be found at 'yourWHMCS/modules/addons/unbanCenter/app/Modules/Sample/Sample.php'.
Owing that, you are able to make your offer much more competitive and extend it to other systems, control panels and servers.

UB2 17.png
Start with renaming the copy of the 'Sample' folder to the name used by your 3rd party module.

Let us say that the folder with the module you wish to integrate with Unban Center For WHMCS is located in 'your_whmcs/modules/servers/' and is named 'DummyIntegration'.
In this case, your folder at 'yourWHMCS/modules/addons/unbanCenter/app/Modules/' should be named 'DummyIntegration'.
The file 'Sample.php' located in the previously renamed folder should be renamed to 'DummyIntegrationUnbanModule.php'.
Afterward, edit the 'DummyIntegrationUnbanModule.php' file and follow the instructions placed inside.

Update Instructions

An essential guidance through the process of updating the module is offered here.

Note: Updating the module from any version prior to 2.0.0 will start the migration process to move settings configured in the previous version to the new one.
These cover: the configuration status, unban type, minimum delay time and option to unban only current IP address. Any created blacklists of IP addresses will not be migrated!
You also need to set recursively writable permissions for storage directory in 'yourWHMCS/modules/addons/unbanCenter/' location.

Keep in mind there is a quick and easy option in our client area that will let you upgrade the license of your module to an open source version at any time - and at a lower price!
To take advantage of it, simply use the License Upgrade button located on the product's page and a discounted invoice will be generated automatically.

Common Problems

1. When you have problems with connection, check whether your SELinux or firewall does not block ports.
2. After update, some functionalities are not working properly.

Cause: Your browser stores old JavaScript in its cache.
Solution: Reload full page by using the appropriate key combination to bypass your cache.

3. If you were using any version of the module prior to 2.0.0, note that after upgrading to the latest version the template integration code is no longer needed.
4. If you are getting 'Syntax error or access violation' errors when using an address in IPv6 format, make sure that MySQL 5.7 or higher version is installed.
5. Imunify360: In case you encounter an error while checking the IP address status: 'Imunify METHOD: GetBlackListBylp CODE: 403', open the templates_c folder and revove the cookies.txt file.
