I was trying to add a line of text under my wiget area at the “youtube widget php file , I must have deleted some code cause my site has gone down.
its coming up with this message on homepage

Parse error: syntax error, unexpected ‘}’, expecting ‘,’ or ‘;’ in /home/focalpoi/public_html/wp-content/themes/purity/functions/widget-youtube.php on line 101
