I’ve got a similar issue. I installed the theme via the theme installer and still get the error. I don’t have the JetPack plugin installed at all. Additionally the default themes will preview but won’t activate – they produce the same error. (Even did a fresh install of WordPress!)
This is the error:
Parse error: syntax error, unexpected T_FUNCTION in /home/content/s/a/l/salcwik/html/wordpress/wp-content/themes/zerif-lite/inc/jetpack.php on line 1
Pulling my hair out….can someone help?
Thanks
