i installed the plugin on my localhost test server.
my operation system is windows xp and use wamp as the server
when i add a form and upload a file via ajax ,the warning appears.
Warning: move_uploaded_file(E:wampwwwwordpresswp-contentpluginscformsattachments/6-2.png) [function.move-uploaded-file]: failed to open stream: No such file or directory in E:\\wamp\\www\\wordpress\\wp-content\\plugins\\cforms\\lib_aux.php on line 286
Warning: move_uploaded_file() [function.move-uploaded-file]: Unable to move 'E:\\wamp\\tmp\\php85.tmp' to 'E:wampwwwwordpresswp-contentpluginscformsattachments/6-2.png' in E:\\wamp\\www\\wordpress\\wp-content\\plugins\\cforms\\lib_aux.php on line 286
it seems that a wrong root was used in the script E:wampwwwwordpresswp-contentpluginscformsattachments/6-2.png
the right one should be E:wamp/www/wordpress/wp-content/plugins/cforms/attachments/6-2.png
