PHP-Fusion v7 is released under the terms and conditions of version 3 of the GNU Affero General Public License. For further information please visit www.fsf.org/licensing/licenses/agpl-3.0.html or refer to the agpl.txt file included in the distribution package. You may alter the code in any way you wish and redistribute it either as is or containing your own modifications but it is mandatory that you retain the "Powered by PHP-Fusion" footer copyright notice as described in the readme file included in the distribution package; or rephrased in such a manner that it does meet the following requirements as stated in
the AGPL license text, as quoted:
Terms of AGPL Copyright Notice
Affero GPL version 3 Chapter 0 - Terms and Conditions
An interactive user interface displays "Appropriate Legal Notices" to the extent that it
includes a convenient and prominently visible feature that (1) displays an appropriate copyright notice, and (2) tells the user that there is no warranty for the work (except to the extent that warranties are provided), that licensees may convey the work under this License, and how to view a copy of this License. If the interface presents a list of user commands or options, such as a menu, a prominent item in the list meets this criterion.
This means that the copyright footer of PHP-Fusion may not be altered in such a way that it doesn't display our copyright notice in a way that isn't "convenient and prominently visible", meaning that no popups linked to graphic images, no tooltip-like solutions linked to images etc, are allowed.
With adherence to that, the Copyright Footer must contain the following:
• "Powered by PHP-Fusion" is optional but is requested for clarity purposes;
• Copyright PHP-Fusion 2002-2013 Nick Jones
- with "PHP-Fusion" linking to http://php-fusion.co.uk;
• Released as free software without warranties;
• Link to the Affero GPL version 3 license;
If the Copyright Notice Footer does not contain the 3 key elements clearly
displaed without the correct licensing will be deemed a breach of contract, your
domain will be added to the copyright violators database and your host will be
informed which could result in your site being removed.
If the Copyright Notice Footer does not contain the 3 key elements as described above, this invalidates the license and could be subject to prosecution by FSF terms.
If you for some reason do not feel comfortable with this solution, please consider to purchase a copyright removal license instead, see below for details.
