Title: Errors on 404 page Last modified: August 30, 2016 --- # Errors on 404 page * Resolved [prunly](https://wordpress.org/support/users/prunly/) * (@prunly) * [11 years ago](https://wordpress.org/support/topic/errors-on-404-page/) * Hi there, * I really like this theme. It is perfect for a project I am working on. The only problem I have had is with the 404 page. There are a lot of PHP errors being generated as follows: * > Notice: Trying to get property of non-object in /path/to/site/wp-content/themes/ > sento/admin/main/options/01.general-settings.php on line 78 * > Notice: Undefined variable: _thinkup_meta_slider in /path/to/site/wp-content/ > themes/sento/admin/main/options/02.homepage.php on line 31 > class=”error404 > logged-in custom-background layout-responsive layout-wide pre-header-style2 > header-style2″> * > Fatal error: Call to undefined function thinkup_input_404content() in /path/ > to/site/wp-content/themes/sento/404.php on line 10 * At this point I removed the call to the undefined function in my child themes 404.php page to solve the fatal error. Then I got the following in the footer of the page: * > Notice: Trying to get property of non-object in /path/to/site/wp-content/themes/ > sento/admin/main/options/01.general-settings.php on line 216 * > Notice: Trying to get property of non-object in /path/to/site/wp-content/themes/ > sento/admin/main/options/01.general-settings.php on line 641 * This is a fresh WP install with WP_DEBUG set to true. All plugins are up to date.

Please can you delete the theme and then re-install. * If this doesn’t work please do let us know. * Thanks! * Thread Starter [prunly](https://wordpress.org/support/users/prunly/) * (@prunly) * [10 years, 12 months ago](https://wordpress.org/support/topic/errors-on-404-page/#post-6226956) * Hi ThinkUpThemes, * Thank you for your response. A fresh install of the theme did not fix the problem. * Turning off debug hides the PHP notices of course but the Fatal error is down to a function that either does not exist or is not being called correctly. Maybe a typo or something? * > Fatal error: Call to undefined function thinkup_input_404content() in /path/ > to/my/website/wp-content/themes/sento/404.php on line 10 * Actually, I just had a look at you official demo and you can see it there too.

It looks like a file is not being called in corrrectly. The issue has now been resolved on the demo site. The next theme update will fix this issue. In the meantime please can you add the following code to your functions.php file: * `require_once( get_template_directory() . '/admin/main/options/08.special-pages. php' );` * Ordinarily we’d ask you to add this via a child theme. however, given that this line will be added to the next update please instead add it to functions.php file in the the core theme folder. * This should resolve your issue. When the next update is released this issue will be resolved within the theme itself so you won’t need to redo this step again. * If you experience any issues please do let us know. * Thanks! * Thread Starter [prunly](https://wordpress.org/support/users/prunly/) * (@prunly) * [10 years, 12 months ago](https://wordpress.org/support/topic/errors-on-404-page/#post-6226958) * Thanks ThinkUpThemes.
