Fatal Error Call to undefined function wp_update_custom_css_post()

    HELP!

    I’ve just updated my theme on WordPress (didn’t change it, just clicked “update now” as it told me it had an available update) and I’ve managed to mess up both my blog page, AND I now can’t even access where I edit my WordPress at all. The url http://www.woodenwindowsills.co.uk now just goes to this error page saying:

    Fatal error: Call to undefined function wp_update_custom_css_post() in /websites/123reg/LinuxPackage23/sp/_a/ce/sp-ace.co/public_html/WoodenWindowSills/wp-content/themes/activello/functions.php on line 125

    Do you have any idea why this has happened or any wisdom for how to sort it?

    I know nothing about the technicalities of websites (I usually just log into my wordpress page and then I’m set), so please explain all solutions in the most basic terms, I’m panicking that I won’t be able to get it back!

    Thanks,

    Alice

    Can you try reinstalling just the theme? You will need FTP access/ access to a file manager through your hosting provider’s control panel.

    Once you have access,

    • Download the theme to your computer: https://wordpress.org/themes/activello/
    • Unzip it
    • Using FTP or your File Manager tool, go to the ‘wp-content/themes’ folder
    • Upload the ‘activello’ (unzipped on your computer) folder there and choose to overwrite/ replace any duplicate file

    I don’t know if you’ve changes to the theme’s files so it’s best to make a backup first.

    Thanks for all of your suggestions, how do I do a backup? I can’t access anything but that error page, whether I try and sign in as I usually would or just on the site itself?

    Copy the existing theme folder using FTP/ your hosting provider’s file manager tool and put it somewhere safe.

    Hi @woodenwindowsills.,

    You can get backup with FTP or CPanel File manager.

    Try to reinstall the theme manually

    Download this theme https://downloads.wordpress.org/theme/activello.1.3.6.zip

    And extract your wp-content/themes folder manually (using FTP)

    Thanks
