Help admin panel

I do not speak English, only Spanish, I will try to explain in simple and clear way to see if someone can help me.

I can not see in the administration panel, members, when I click on members, I get an error from the database

I searched in the forum, but have not found anything about it, hopefully someone can help, thank you very much for your assistance.

Hello

If you provide me with error message itself I'll try to help you.
You may contact me via internal mailbox.
