The plugin generated 12800 characters of unexpected output

    I am getting the following error when I install the plugin:

    The plugin generated 12800 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.

    On every page of the admin panel, the plugin code is dumped on the top of the screen, pushing everything else down. Not only that, it’s dumping the code at the top of the public website.

    I deleted the plugin and downloaded it again to give it another try. I got the same results.

    Any idea why this would be happening?

    Not yet, cause the plugin isn`t doing anything in the frontend, but inserting some js.

    Can you send me a screenshot of this happening? First time i hear about this problem, maybe some craziness with another plugin?!

    Just checked back at the code, just to find out that the plugin isn`t even doing anything on activation…;)

    Not even a single line of code is executed on activation…strange. A screenshot of the output would be nice.

    Might be your solution:

    The plugin generated xxxx characters of unexpected output during activation.

    Try deactivating and reinstalling the plugin. Sometimes characters can get appended to a file when you use the standard FTP transfer. Please transfer using binary mode or just use the WordPress plugin uploader

    Thank you for checking into the issue. I tried to download the plugin again I got the same result. No matter if I FTP or download from the repo.

    I have removed the plugin for now but will try and re-install in on another site and see what happens.

    Here’s your problem(s) and solutions:

    1) In several defined constants you have a typo SUPPAT instead of SUBPAT.

    2) Also you should check if $_GET var subtle_msg is set before checking its contents.

    3) And there’s a starting bracket missing for a P tag in subtle-backgrounds-admin.js:
    + ‘/p>’

    4) You are using PHP short tags, ie. <?. Always use full tags <?php as a lot of hosts have PHP short tag support disabled.

    Fix those, then deactivate and reactivate the plugin and the errors are gone (for me anyhow).

    Thx for the fixes kraterdesign, will be added in upcoming version…

    My guess were the PHP short tags on srumery`s problem.

    Fixed in 1.2!

    You’re welcome!
