Update fail!

HI
I am updating my piwik to 2.4.1. Now he said me:

  1. Undefined index: datatable_row_limits in /home/mhd-01/www.linopolo.net/htdocs/analytics/core/Config.php on line 223
    2)Undefined index: adding_segment_requires_access in /home/mhd-01/www.linopolo.net/htdocs/analytics/plugins/SegmentEditor/API.php on line 130

what I have to do?
thanks

This normally is only a warning so you don´t have to do anything. But I am not sure if this causes problems in Piwik.
Do you have any problems with Piwik?

He said "There is an error. " and the other things I wrote.
It’s annoying because It’s a really big message!!!
Thanks

It´s not yet clear to me if you have problems now when using Piwik. Do you mean that there is a big error message displayed in yellow on every page?

the datas are ok. but the big message in yellow is big and annoying.
Thanks

Wild guess: Maybe a file is missing?

Re-upload the file config/global.ini.php from the latest piwik.zip package
