That's a partial blank page problem, I think. Check your /cache folder for error log files.

here is it:

any help?

Please reinstall a clean copy of the missing file from the error message:
/includes/index_filters/default_filter.php

and see if this fixes the problem or you get a new error message in the:
/cache

when you refresh this directory in your FTP program ...

same error appeared and I want to ask, why the error show includes inside incldues, shouldn't it be just one?

Could you look in the /cache and refresh it in your FTP program then open the most current debug log by date and copy and past the error messages here?
