HI Silks,
I’ve split your reply and created a new topic to keep some order in the forum.
The error you see is related to Google Analytics statistics, not to you being able to login or not.
Your login / register page is: yoursite.com/?geodir_signup=true
Or you can add the GD > Loginbox to any of your sidebars.
To remove that analytics error, you must ask your server admin to disable safe_mode from your server. That will remove the error.
To remove the login failed message appearing below the error, you can eiter disable Google Analytics option or set it up correctly so that it can show statistics:

Please avoid posting in old topics (especially if they have nothing to do with your current problem).
Thank you!
