Or are you using a theme or plugin that allows you to edit content on the frontend? * Thread Starter [flacoman91](https://wordpress.org/support/users/flacoman91/) * (@flacoman91) * [8 years, 4 months ago](https://wordpress.org/support/topic/easy-footnotes-php-undefined-offset-0-error/#post-9903966) * I’m just trying to save a post in the standard WordPress dashboard. * After I hit Publish/Save, it goes to white screen. with the following errors. * I have WP_DEBUG turned on in wp-config.php * Notice: Undefined offset: 0 in /var/www/html/wp-content/plugins/easy-footnotes/ easy-footnotes.php on line 72 * Notice: Undefined offset: 0 in /var/www/html/wp-content/plugins/easy-footnotes/ easy-footnotes.php on line 72 * Notice: Undefined offset: 0 in /var/www/html/wp-content/plugins/easy-footnotes/ easy-footnotes.php on line 72 * Notice: Undefined offset: 0 in /var/www/html/wp-content/plugins/easy-footnotes/ easy-footnotes.php on line 72 * Notice: Undefined offset: 0 in /var/www/html/wp-content/plugins/easy-footnotes/ easy-footnotes.php on line 72 * Notice: Undefined offset: 0 in /var/www/html/wp-content/plugins/easy-footnotes/ easy-footnotes.php on line 72 * Warning: Cannot modify header information – headers already sent by (output started at /var/www/html/wp-content/plugins/easy-footnotes/easy-footnotes.php:72) in / var/www/html/wp-includes/pluggable.php on line 1216 * Plugin Author [Jason Yingling](https://wordpress.org/support/users/yingling017/) * (@yingling017) * [8 years, 4 months ago](https://wordpress.org/support/topic/easy-footnotes-php-undefined-offset-0-error/#post-9903996) * Hmm that is odd. I’m not able to recreate the issue on my end. Could you let me know what theme you’re using and if you have any plugins or anything that display the shortcode within the content editor? * You can try replacing line 72 of easy-footnotes.php with this `if ( isset($shortcodes[ 1][0]) && $content === $shortcodes[1][0] ) {` * But since I’m not able to recreate the issue I haven’t been able to test that yet. * Would you mind sending me the code that is currently on line 72 of your file as well? There isn’t anything there that should be outputting header information as the warning shows. * Thread Starter [flacoman91](https://wordpress.org/support/users/flacoman91/) * (@flacoman91) * [8 years, 4 months ago](https://wordpress.org/support/topic/easy-footnotes-php-undefined-offset-0-error/#post-9904341) * ok, thanks for your help. * I started deactivating all of the plugins on my site. I have Yoast SEO installed as well. It seems that when it is enabled the error gets thrown when I save or update a post. * Deactivating it does not have the error appear. * Doing a var_dump($shortcodes); die(); just shows an empty array. array(2) { [ 0]=> array(0) { } [1]=> array(0) { } } * line 72 is just `if ( $content === $shortcodes[1][0] ) {` * Yes, just checking if the value exists fixes the error/warning. * Thanks. * Plugin Author [Jason Yingling](https://wordpress.org/support/users/yingling017/) * (@yingling017) * [8 years, 4 months ago](https://wordpress.org/support/topic/easy-footnotes-php-undefined-offset-0-error/#post-9906481) * Awesome! Thanks for all the info. I usually have Yoast on, but probably didn’t on that test site so I’ll give it a shot with Yoast installed and work on getting an update out soon. * I appreciate the feedback. * [physalis](https://wordpress.org/support/users/physalis/) * (@physalis) * [8 years, 2 months ago](https://wordpress.org/support/topic/easy-footnotes-php-undefined-offset-0-error/#post-10041074) * Any news? Getting this error debug mode on, too :(. Replacing the line surely helps at least in my case. * Plugin Author [Jason Yingling](https://wordpress.org/support/users/yingling017/) * (@yingling017) * [8 years, 1 month ago](https://wordpress.org/support/topic/easy-footnotes-php-undefined-offset-0-error/#post-10192437) * This portion of the code has been reworked in version 1.0.16 so you should no longer be getting the error.
