Add filter problems

[mvlcek]

Hello,
I am having problems in a web with this: add_filter('content','functionmy');


In functionmy($content), $content is empty, and then does not filter neither, and always writes the content of page.


I am using GS 3.0. In localhost it works good, but in server not; can you give me some idea?.

Thanks.

Maybe you have another filtering plugin installed that outputs the content and returns nothing instead of returning the content. Try removing the other plugins and try again.
