Deprecated: Function ereg() is deprecated in
Try replacing line 16-17 in catalog/includes/application_top.php and admin/includes/application_top.php
// set the level of error reporting error_reporting(E_ALL & ~E_NOTICE); To // set the level of error reporting error_reporting(E_ALL & ~E_NOTICE & ~E_DEPRECATED); Looking at the long list of deprecated features in PHP 5.3.0. I get the impression that if you want to replace all the code with deprecated functions we might as well do a total rewrite and use superglobals everywhere. But then we might as well better start using osC v3. Pity there doesn't seem to be any progress in that area So for the time being I believe adding the ~E_DEPRECATED will at least be needed too. Frankly, I'm amazed that these are the only error messages since for example all the session_ functions are deprecated too.
