Unexpected output on acivate plugin (3 posts)

    When activating my plugin and only if wp debug mode is on, i get the message:

    The plugin generated 255 characters of unexpected output during activation.
    If you notice “headers already sent” messages, problems with syndication feeds or other issues,
    try deactivating or removing this plugin.

    I did not see the headers already sent message, or the other possibilities mentioned in the message.

    The plugin works as expected.

    I would like to read those 255 chracters to see where they come from and so be able to repair for this error message.

    Where do i find the 255 characters?

    An interesting take on the same issue... I don't know how helpful it will be.

    The plugin generated xxxx characters of unexpected output

    There were several hits in the forum search as well.. might be something in there that's useful.

    the plugin generated "characters of unexpected output during activation"
