Hi Suman,
Sure, that’s fine giving you the admin login and ftp. I will set private reply to you.
But before I send you my details, do I need to install the HIDE_MY_WP plugin back in first? If I do, It will get 500 error again? Then how can you login to the admin to fix it? The hosting have to fix the login and you not at the same time?
Please let me know some details so I know?
Thanks Jimmy
