Help!

I can’t have access to my website. When I type the address it always shows this: Parse error: syntax error, unexpected ‘{’ in /home/lirengne/public_html/wp-content/themes/sydney/widgets/fp-call-to-action.php on line 122
on a blank page. What should I do to go back my site?

Did you changed something in this file or installed a new plugin?
Then access your server via FTP and delete the fp-call-to-action file or the new plugin you installed. Then download sydney again and copy the new file on the server.
