我编辑functions.php但无法访问

I was doing editing to function.php file and when I refreshed it, it gives me error and now I can't get into wp-admin it is giving me same error whenever I am trying to get into my website. My website is www.studentsbaithak.com

I am understanding the error but there is no such '<' sign in the file and it keep on giving the same error. I can't log in to my wp-admin dashboard.

This is the error:

Parse error: syntax error, unexpected `'<'` in
`/home2/students/public_html/wp-content/themes/flex-lite/functions.php
on line 179`

Edit function.php using FTP (use filezilla) or through cpanel.

For edit file you can you either use cpanel or FTP. If you are in cpanel then find public_html or html folder in that your side folder. Now from site folder Wp-content->theme->functions.php here theme folder means it should be your active theme folder. there you can edit your functions.php file after that you are able to login again in your wp-admin. Hope this will helps you.
