Sharing this issue with you, to make you aware, and perhaps there is a fix?
When I try to save a Page that uses Visual Composer shortcodes, I get error:
“Warning: Cannot modify header information – headers already sent by (output started at …/public_html/wp-content/themes/Newspaper/includes/wp_booster/td_block.php:149) in …/public_html/wp-admin/post.php on line 197
Warning: Cannot modify header information – headers already sent by (output started at …/public_html/wp-content/themes/Newspaper/includes/wp_booster/td_block.php:149) in …/public_html/wp-includes/pluggable.php on line 1171”
I have discovered that if I open this file:
/Newspaper/includes/wp_booster/td_block.php
and comment out this line:
// echo the default style of the block
// disable this line fixes page save echo $this->block_template()->get_css();
return '';
}
.. then I able to save VC pages without error.
I wonder if anyone else has this error? Or perhaps something unique to my environment. Anyway glad I am able to fix this way, for now. Thanks!
Hello jgreenwood,
Please ensure that you are using the latest version of the theme with the latest version for required plugins (Visual Composer 4.11.2 and Social Counter 4.1). Also, please make sure this type of error does not come from your untested plugins. Please try to disable all the active plugins, leave just Visual Composer to active, clear all your caches, purge CDN files if you are using the CDN system and install only the plugins that come bundled with our theme and rule out the conflicting plugins.
Hope this helps and let us know how it goes!
Thanks for your understanding!
