Errors after installation to live server

Hi,
I have installed my site to a live server, after developing on a local server and it worked fine.
I have errors showing after setting error reporting to development.
Strict Standards: Only variables should be assigned by reference in /hsphere/local/home/ervale/joomlatest.sunshinecoastwebdesign.com.au/plugins/system/osmembershipreminder/osmembershipreminder.php on line 30 Strict Standards: Only variables should be assigned by reference in /hsphere/local/home/ervale/joomlatest.sunshinecoastwebdesign.com.au/components/com_osmembership/helper/helper.php on line 22 Strict Standards: Only variables should be assigned by reference in /hsphere/local/home/ervale/joomlatest.sunshinecoastwebdesign.com.au/components/com_osmembership/helper/helper.php on line 944 Strict Standards: Only variables should be assigned by reference in /hsphere/local/home/ervale/joomlatest.sunshinecoastwebdesign.com.au/components/com_osmembership/helper/helper.php on line 1016
If i switch off error reporting from developer i get a 500 server error

joomlatest.sunshinecoastwebdesign.com.au/

Latest Joomla 3
I have installed a new Joomla! 3.0.4 first and worked fine, if i disable /plugins/system/osmembershipreminder i get a 500 error on the front page but the backend works fine.

Can you take a look please
Regards
Dave

Hi,
Not your problem, the problem seems to be in error reporting, i have switched error reporting from developer to Maximum and it works,
