WampServer

Hi,

I'm a newbie to PHP and Apache. Have installed Wamp. Was running OK. Now am getting the following message when I try to get into phpMyAdmin:

Cannot start session without errors, please check errors given in your PHP and/or webserver log file and configure your PHP installation properly.

I can't find anything in the PHP error log. In fact is says that it does not exist.

Can you please direct me to where I should look and docos for help with error messages.

Thanks for you help.
