I have a PHP application which I have developed and released under the LGPL, currently on the bottom of the web pages it has a copyright line. Is this allowed or can I only put the copyright line in the source file.
Another part to this question is under LGPL is the user allowed to remove the Copyright line from the web pages, as long as they leave it in the source files.
A cursory look through the GNU licenses didn't turn up anything definite regarding your question. I have seen CMS templates released under the GNU license with a note not to remove the copyright without the copyright owner's express permission. Other CMS templates released under the GNU license grants permission to remove copyright notice.
If you do display your own copyright on the web pages, you will need to display the GNU license info along with it.
