quite often, you will find the code for that in footer.php of your theme.
if it is not in footer.php, it might get added via an action hook or whatever – my dowsing rod is a bit rusty so I can’t divinate which theme you are using…
please post the name of the theme you have the actual problem with.
Adventure
When I update footer.php nothing happens
your theme is a commercial theme which makes helping through this forum virtually impossible, because the theme files are not freely accessible so nobody can just download the theme to have a look.
your best bet is to approach the theme seller for support with your commercial theme.
i downloaded it through the repository
i’m not sure what you mean, is there a plugin that can fix this?
I mistaken the theme for a commercial one with the same name 🙁
just to answer the question:
in the case of the theme ‘Adventure’ from the repository http://ww.wp.xz.cn/extend/themes/adventure, the ‘powered by WordPress’ is in index.php
