What beta platform have you installed Francisco? What errors or issues do you have, please be more specific. 

Please stop duplicating your posts, I already told you that your DB has been corrupted, you don't have any profile questions right? I recommend to restore a backup

this problem is from weeks ago and ross answered it in one post and in another i answer 
and 2 days ago i answered it again
i will answer it yet again
i looked at your site 3 weeks ago and you have played with your db so much you have messed everthing up you need put a backup of your database 

and i answered you on what a batabass is 

and on what to do if you dont have a databass backup 

lol ross u faster typer then me 

Provide a screenshot of your profile questions section in the admin panel please?

that is still the same problem you have just put backup of script in and not databass

here not open

Same problem, your database is corrupted, do you have a proper backup of the database and files, please restore it. 

how to do it and at what location?

what do you mean what location, contact your hosting provider and ask them to restore the backup, which does not have such a problem, I don't know of which date it should be.
