where is axactly the file? 
already made changes here:

any Suggestion?

Hello,

The copyright sentence is in the file "/templates/sparky_framework/library/c.php". If it doesn't change after you change it then you either didn't upload the modified file correctly, or you have some kind of caching enabled for your website.

Sorry, i created an individual column for a copyright text under footer module. .. naturally has not a relation with the File c.php. Anyway, good to know about Milos.

What is the solution?
