However, changes on “Countdown” theme can’t be saved. Do you have any idea how to make this work? Many thanks! * The page I need help with: _[[log in](https://login.wordpress.org/?redirect_to=https%3A%2F%2Fwordpress.org%2Fsupport%2Ftopic%2Fcountdown-theme-doesnt-work%2F%3Foutput_format%3Dmd&locale=en_US) to see the link]_ Viewing 8 replies - 1 through 8 (of 8 total) * Plugin Author [NiteoThemes](https://wordpress.org/support/users/niteo/) * (@niteo) * [7 years, 7 months ago](https://wordpress.org/support/topic/countdown-theme-doesnt-work/#post-10801497) * Hello [@ibro87](https://wordpress.org/support/users/ibro87/), did you click on a select theme ? and then click on the button “Save all the changes”.

If there is there anything I can do to save the changes please do let me know.

I am getting the following error after saving changes: “Fatal error: Call to undefined function sanitize_hex_color() in /home1/ibro/public_html/wp-content/plugins/cmp- coming-soon-maintenance/cmp-settings.php on line 273” I just realized that the same problem occurs with “Construct” theme as well. * However, “Hardwork” theme works perfectly fine on all browsers so I will just stick to this theme for now. Thanks for your help and keep up the good work! * Plugin Author [NiteoThemes](https://wordpress.org/support/users/niteo/) * (@niteo) * [7 years, 7 months ago](https://wordpress.org/support/topic/countdown-theme-doesnt-work/#post-10806046) * OK, that helps! `sanitize_hex_color()` function is available since WordPress version 4.6 (currently 4.9.8) so you must run quite old WordPress installation. * I will make update to our plugin to catch this error as soon as possible but it would be best, if you could update your WordPress to latest version anyway 🙂 * Alex * Thread Starter [ibro87](https://wordpress.org/support/users/ibro87/) * (@ibro87) * [7 years, 7 months ago](https://wordpress.org/support/topic/countdown-theme-doesnt-work/#post-10809041) * Hi there, * Updating WordPress to 4.9.8 version fixed the problem.

I am glad you bring up this isssues – I will make update anyway for better compatiblity with older WP installations. * Btw thanks for your review! * cheers Alex * Moderator [Jan Dembowski](https://wordpress.org/support/users/jdembowski/) * (@jdembowski) * Forum Moderator and Brute Squad * [7 years, 3 months ago](https://wordpress.org/support/topic/countdown-theme-doesnt-work/#post-11209691) * [@niteo](https://wordpress.org/support/users/niteo/) I’ve deleted your offer to login to your user’s site and I’ve temporarily flagged your account.
