 * Hi, what membership levels do you have set up? Do you have a cache plugin installed?
   If you do have a cache plugin you have to exclude membership login pages and 
   registration pages from the cache plugin.

   yet. – One more thing. all my custom code of plugin are removed. and new folder

 * I think what you should do is uninstall and delete the plugin. Then install a
   fresh new copy.
 * Let me know how you go.
