I’m not sure why it would generate an error there as $atts should always be an array, but you can try this: * Change * `foreach ( $atts as $attribute => $value ) {` * To * `foreach ( (array) $atts as $attribute => $value ) {` * Let me know. * Thread Starter [apartmentsforrentx](https://wordpress.org/support/users/apartmentsforrentx/) * (@apartmentsforrentx) * [6 years, 11 months ago](https://wordpress.org/support/topic/php-error-330/#post-11673723) * Hi, * This is a bit alarming.

Otherwise I can’t see an actually security issue here. * Am I missing something? * Also crappy temporary hack but since we have seen this error a few times with no real reason why it should occur would it be possible for you to paste the shortcodes used on your site from our plugin. * And if possible add in a var_dump($atts) exit; then load the page where it should be rendered. Instead it will simply output the variable $atts and end. Copy that here and delete the var_dump and exit lines. * Let me know.

But, my website’s security is at stake, since 2 days ago, 20 daily hack attempts are reported by my security plugin. Which is very unusual and alarming. We know that different hack methods are on the web, and one reason is due to the directory path being exposed. But if it is not too much to ask from you. Could you please edit my first post and just remove the directory path before * “/wp-content/plugins/content-control/classes/Shortcodes.php on line 69” * I would appreciate it. Thank you. * Thread Starter [apartmentsforrentx](https://wordpress.org/support/users/apartmentsforrentx/) * (@apartmentsforrentx) * [6 years, 11 months ago](https://wordpress.org/support/topic/php-error-330/#post-11681496) * Additionally I had 7 reported directory traversal hack attempts on my website. So I hope you could grant my request to remove the directory path on my first post. Thank you. * Moderator [Jan Dembowski](https://wordpress.org/support/users/jdembowski/) * (@jdembowski) * Forum Moderator and Brute Squad * [6 years, 11 months ago](https://wordpress.org/support/topic/php-error-330/#post-11681730) * [@apartmentsforrentx](https://wordpress.org/support/users/apartmentsforrentx/) Stop reporting this topic. * Again, there is nothing here that us security related. Please do not report this again. * Those probes happen regardless and if you are concerned then considered hardening your site and/or installing a security plugin. * [https://wordpress.org/support/article/hardening-wordpress/](https://wordpress.org/support/article/hardening-wordpress/) * [https://wordpress.org/plugins/search/security/](https://wordpress.org/plugins/search/security/) Viewing 8 replies - 1 through 8 (of 8 total) The topic ‘PHP Error’ is closed to new replies. * ![](https://ps.w.org/content-control/assets/icon-256x256.gif?rev=2968535) * [Content Control - The Ultimate Content Restriction Plugin!
