Cannot edit site

See Changing The Site URL ? WordPress Codex for recovery instructions.

Hi hibba123,

It seems your url couldn’t saved appropriately,
Please check your database in wp_options table and see if the “option_value” column next to “siteurl”
and next to “home”, is same what you changed through setting. If not then please take the backup of your db
and then change that value according to need.

I think, you need to redefine the path for wordpress in root directory.
