    Hey,

    is it allowed under the GPLv2 License to modify anything on my wordpress installation and resell it?
    Could you give me an advice which part of the license includes this? Do I only have to add the GPL License in the root of the wordpress folder?

    Thanks in advance,
    Steve

    Have you looked at the license page and the linked resources/info?

    Hey WPyogi,

    thanks for your fast answer.

    <<looked at the licence page?>>
    Yes I did. And on the linkings too. Especially to the gnu.org linkings/FAQs

    In my case I interpret that it is allowed under GPL Licence. But 2 aspects are essential:
    1) the GPL Licence must be attached or at least the linking to the terms.
    2) the source code must be published to the world (?). How can I do this? Does it mean the source code has to be put on git or any other known network?

    Thanks in advance again,
    best..

  4. is it allowed under the GPLv2 License to modify anything on my wordpress installation and resell it?

    Yes, as long as your modifications do not do something like encrypt or obfuscate the code and you do not put restrictions on the code including your own modifications. That encryption or obfuscation would restrict the freedom of the end user. That's a no-no for the GPL.

    Also you must maintain the credit for that code as it wasn't yours to begin with.

    So if you modify any GPL code and sell it you can't say to your customer "you may not distribute or modify what you have bought" or restrict the use and/or modification of that code in any way.

    2) the source code must be published to the world (?). How can I do this? Does it mean the source code has to be put on git or any other known network?

    You're in luck: with PHP it's not a compiled binary. ;) So any PHP that you distribute will be readable in any text editor and the user will have the source code already because you've given it to them.

    Thank you Jan for the extended and interesting information.

    In one point I am not sure if it is allowed. You said:

    Also you must maintain the credit for that code as it wasn't yours to begin with.

    So if you modify any GPL code and sell it you can't say to your customer "you may not distribute or modify what you have bought" or restrict the use and/or modification of that code in any way.

    In this case I have to keep the message that it is powered by WordPress + Logo etc? (don't worry, I love wordpress very much, it's just because I want to see the possibilities which are possible).

  6. No, you just have to credit it in the code itself.
