Generally these errors should not have any affect and what you just need to turn them off error reporting, to get your site functioning.
This could be done from the php.ini file. Php->Apache->php.ini file.
Look for the below lines
error_reporting = E_ALL | E_STRICT
display_errors = On
and change them to
error_reporting = E_ALL & ~ E_STRICT
display_errors = Off
Hope this helps
