Hi,

the error let me think that you still have a very old version of PHP installed on the server. Probably you have still PHP 5.2 that doesn't support normal syntax.

To fix the problem and reinstate quickly the site simply connect through FTP and delete the folder:
/home/niziki/domains/maalot.biz/public_html/plugins/system/screenreader/

You dont' need to restore the site backup.

Before installing and activating it again ensure to have at least PHP 5.3 installed.
