i was creating a blog for a customer of mine, all was perfectly working from january, yesterday my customer changed his instagram username and today the blog gives this error:
Warning: Cannot modify header information - headers already sent by (output started at /home/content/23/10324823/html/wp-content/plugins/copygram-widget/copygram-widget.php:757) in ..../index.php on line 18
i've changed all params in copygram and widget, if i go to copygram site all is working, the new username is correctly displayed and all pics are listed
The very strange thing is that if i reach directly a page of the blog, for ex. index.php?p=xxx the copygram widget is perfect, and i have no errors, but if i reach the home page (that starts with the latest post, the one that i see correctly if directly reached with ?p=xxx) i have only the error and nothing is displayed
Please help me, thanks
p.s. sorry for my bad english!
