Multicraft Bug Bounty Program

22. May 2015
As a last step before the finalization of the new release we have ordered a security review for Multicraft and we have launched a Bug Bounty program with the good folks over at Bugcrowd.
The program has initially been launched as private so if you're interested in participating and earning monetary rewards for reporting security critical bugs please head over to to register for a researcher account. Once you have done so please let us know so we can add you as a researcher to our program.

The bug bounty program will be made public in the future once we have left the initial selection of researchers enough time to review the code.

Blesta Multicraft Module - Updated

29. September 2014
We are happy to announce that the good folks over at Blesta have developed a module to fully support Multicraft with their billing software platform. A video of the module in action can be seen in their blog entry regarding this development:
Blesta Blog: New Multicraft Module

The module is part of the official v3.3 release of Blesta so you do not have to install any addons to use this module. If you are using an older version of Blesta you can download the module separately from this forum post.

The documentation for this new module can be found here:

You can try the new module without obligation by installing the free trial of Blesta and connecting it to your existing Multicraft installation.

We will also be sending out 15% discount coupons for Blesta owned licenses with every new purchase of any Multicraft license.

BukGet API changes

26. February 2014
The implementation of the BukGet browser in Multicraft has been updated to the latest version of the BukGet API. This will also fix the issues that recent changes in the BukGet API have caused for most users of the built-in plugin browser.

You can download a package with a set of updated files here:

Simply replace the existing files of your panel with the files from this archive by extracting the archive into the front end directory of your Multicraft installation (by default /var/www/multicraft or /var/www/html/multicraft).

Bukkit 1.7

01. December 2013
If you are experiencing issues with the server status display when running Bukkit 1.7 that means your configuration files are outdated. You can simply update them under "Settings"->"Update Minecraft" by selecting your current JAR file and ".conf files", then clicking "Download" and "Install" as soon as the download is ready.
If you are using a different JAR file name you need to make sure that you use an updated .jar.conf file with the same name. You can simply copy it from the official craftbukkit.jar.conf or minecraft_server.jar.conf depending on your server type. For more information, please see Custom JAR Files.

BukGet URL change

12. November 2013
The URL for the BukGet API version 2 has changed, causing the BukGet browser to malfunction. To fix this you can simply edit the file protected/models/BgPlugin.php of your panel and change:
    static $apiUrl = '';
    static $apiUrl = '';
at the top of that file.

Minecraft 1.7

25. October 2013
If you are experiencing issues with the server status display when running Minecraft 1.7 that means your configuration files are outdated. You can simply update them under "Settings"->"Update Minecraft" by selecting your current JAR file and ".conf files", then clicking "Download" and "Install" as soon as the download is ready.
If you are using a different JAR file name you need to make sure that you use an updated .jar.conf file with the same name. You can simply copy it from the official craftbukkit.jar.conf or minecraft_server.jar.conf depending on your server type. For more information, please see Custom JAR Files.
