Unless you either provide a link to the problem site or the complete error message (use the pastebin if it a long message), we can’t really help,

so i need to copy the whole page w all the errors and invalid urls, isnt their valuable info their? i just dont know if its safe

Nope. If it’s already a public site and indexed by search engines, all you need to do is just leave a link so someone else can go and see what’s happening.

could you see the errors?

Try:
– switching to the Twenty Eleven theme by renaming your current theme’s folder in wp-content/themes and adding “-old” to the end of the folder name using FTP or whatever file management application your host provides.

– resetting the plugins folder by FTP or phpMyAdmin.

im in my file manager i found the folder twenty eleven but i dont know how to rename it to add -old how do i add it in my file manager?

Were you using Twenty Eleven previously? Have you tried resetting the plugins folder?

i still cant figure this out i dont know what the problem is?????
