I have a gibbon software but it shows me error at index.php line 610 error was unnecessary ? When i removed this it shows error again on other page. And then every line by line. But error was same.

Hello, are you able to tell us what the error with line 610 is? If you cannot see it on screen, it should be recorded in your PHP logs.

It would also be useful to know what version of PHP you are running, and which version of Gibbon.
