Title: Error on certain pages Last modified: August 14, 2020 --- # Error on certain pages * Resolved [wpusr1](https://wordpress.org/support/users/wpusr1/) * (@wpusr1) * [5 years, 9 months ago](https://wordpress.org/support/topic/error-on-certain-pages/) * Hello.. First thank you very much for the plugin. I had installed it on my site which I was developing along with Contact Form 7. But I suddenly get this error on some pages: * ``` Need to Make an Enquiry? There has been a critical error on your website. Please check your site admin email inbox for instructions. Learn more about debugging in WordPress. ``` * I checked error log and saw this with today’s date: * ``` [14-Aug-2020 06:32:45 UTC] PHP Fatal error: Uncaught Error: Call to a member function prop() on null in /home/.../wp-content/plugins/cf7-grid-layout/public/class-cf7-grid-layout-public.php:332 Stack trace: #0 /home/.../wp-includes/class-wp-hook.php(289): Cf7_Grid_Layout_Public->cf7_shortcode_request('[contact-form-7...', 'contact-form-7', Array) #1 /home/.../wp-includes/plugin.php(206): WP_Hook->apply_filters('[contact-form-7...', Array) #2 /home/.../wp-includes/shortcodes.php(355): apply_filters('do_shortcode_ta...', '[contact-form-7...', 'contact-form-7', Array, Array) #3 [internal function]: do_shortcode_tag(Array) #4 /home/.../wp-includes/shortcodes.php(218): preg_replace_callback('/\\[(\\[?)(contac...', 'do_shortcode_ta...', '[contact-form-7...') #5 /home/.../wp-content/themes/../contact-forms/cs_layout2.php(47): do_shortcode('[contact-form-7...') #6 /home/.../wp-content/p in /home/.../wp-content/plugins/cf7-grid-layout/public/class-cf7-grid-layout-public.php on line 332 ``` * I am not sure if the error is related to CF7 plugin.. (apologies if it isn’t) but it goes away once I deactivate the plugin. Strangely this error only happens on some pages. I am just starting on with my site. Only the homepage is done which shows no errors. But when I click on some other pages to edit (with elementor) this error comes up. I’m not a WordPress expert.. Kindly help if you can. Thanks a lot.

But the error message contains the plugin name. So it may not be a plugin related issue? I will copy the updated shortcode and let you know.

Please check your site admin email inbox for instructions. * the entire stack trace is referring to the ‘contact-form-7’ shortcode, right from the WP core files themselves….so yes, defeinitely a cf7 form shortcode is being called and I reckon it is outdated. Hence the error. * Thread Starter [wpusr1](https://wordpress.org/support/users/wpusr1/) * (@wpusr1) * [5 years, 9 months ago](https://wordpress.org/support/topic/error-on-certain-pages/#post-13261313) * Thank you for your time and patience. I will remove the contact-form-7 plugin and reinstall along with CF7 Smart Grid Extension and check. Will keep you posted. Thanks again.. * Plugin Author [Aurovrata Venet](https://wordpress.org/support/users/aurovrata/) * (@aurovrata) * [5 years, 8 months ago](https://wordpress.org/support/topic/error-on-certain-pages/#post-13266496) * sure. I will try in the next major release (v4.0 currenlty under development) to provide a more robust way to handle outdated shortcodes with a clean warning mechanism.
