Did you change your admin/includes/configure.php to match the new directory?
Change
Code:
// NOTE: be sure to leave the trailing '/' at the end of these lines if you make changes!
// * DIR_WS_* = Webserver directories (virtual/URL)
// these paths are relative to top of your webspace ... (ie: under the public_html or httpdocs folder)
define('DIR_WS_ADMIN', '/mysite/admin/');
define('DIR_WS_CATALOG', '/store/');
define('DIR_WS_HTTPS_ADMIN', '/mysite/admin/');
define('DIR_WS_HTTPS_CATALOG', '/store/');
to
// NOTE: be sure to leave the trailing '/' at the end of these lines if you make changes!
// * DIR_WS_* = Webserver directories (virtual/URL)
// these paths are relative to top of your webspace ... (ie: under the public_html or httpdocs folder)
define('DIR_WS_ADMIN', '/admin/');
define('DIR_WS_CATALOG', '/');
define('DIR_WS_HTTPS_ADMIN', '/admin/');
define('DIR_WS_HTTPS_CATALOG', '/');
and see if that does the trick.
