Hello,
The one issue was that you have setup
Use HTTPS on payment pages to yes in payplans configuration. I have disabled it because ssl applied to entire site so no need to set it here.
You have applied haccess at your site , when i try to login after renaming httaccess file it giving the error.
You are a spammer, hacker or an otherwise bad person.
Please try again to remove after removing htaccess and and restriction's you made.
Update me.
