wp-admin error

Look at your wp-config.php around line 35 and remove the blank line / space and re-save the file.

doesn’t work
theres nothing on line 35

Yes there might not look as if there is anything on line 35. Indeed, it might just be a blank line. But there is something after the closing ?> that is sending output.

If not, there is no explanation for your error.

You could also try removing the the ?> if you can’t see the blank line in your editor.

removed it same error
