    Hi there,

    I decided to reset my website as I kept having multiple problems with updates on the Jupiter X Core Plugin. I didnt want to reset the whole site but i am not technical with the backend and coding of wordpress sites but didnt know what else to do. The website was due a revamp anyway. So, Ive stripped everything back down to scratch including all the plugins thinking that would help maybe solve the problem with Jupiter X Core plugin but no, when ive done the update again on it it says this:

    An error of type E_ERROR was caused in line 17 of the file /var/www/wp-content/plugins/jupiterx-core/includes/customizer/settings/pro/popup.php. Error message: Uncaught Error: Call to undefined function jupiterx_upgrade_link() in /var/www/wp-content/plugins/jupiterx-core/includes/customizer/settings/pro/popup.php:17 Stack trace: #0 /var/www/wp-content/plugins/jupiterx-core/includes/customizer/settings/settings.php(82): require_once() #1 /var/www/wp-content/plugins/jupiterx-core/includes/customizer/functions.php(52): require_once('/var/www/wp-con...') #2 /var/www/wp-includes/class-wp-hook.php(288): jupiterx_core_customizer_include('') #3 /var/www/wp-includes/class-wp-hook.php(312): WP_Hook->apply_filters(NULL, Array) #4 /var/www/wp-includes/plugin.php(478): WP_Hook->do_action(Array) #5 /var/www/wp-settings.php(523): do_action('init') #6 /var/www/wp-config.php(95): require_once('/var/www/wp-set...') #7 /var/www/wp-load.php(37): require_once('/var/www/wp-con...') #8 /var/www/wp-admin/admin.php(34): require_once('/var/www/wp-loa...') #9 /var/www/wp-admin/plugins.php(10): require_once('/var/www/wp-adm...') #10 {main} thrown


    I am not very technical with all the coding and back end of wordpress websites and have no idea how to solve this.

    Please help I just want to start designing my website again!

    Hello Pawel,

    Please make sure your theme is updated to the latest version 1.17.1 and required plugins as well.

    How to update the theme you can find in these articles:
    1. Automatic update ​https://themes.artbees.net/docs/updating-jupiter-x-theme-automatically/

    2. Updating via WP Dashboard ​https://themes.artbees.net/docs/updating-jupiter-x-theme-via-wordpress-dashboard/

    3. Updating via FTP ​https://themes.artbees.net/docs/updating-jupiter-x-theme-via-ftp/

    When the theme is updated you can update required plugins in the Jupiter X > Control Panel > Plugins section.

    Important! Don’t forget to create full site backup including the database before starting the update process.


    If you have any difficulties then provide us with wp-admin and FTP (FTP host, FTP user, FTP password, FTP port) login details to your site in the private reply https://prnt.sc/qr3w3e to check the issue.

    I just had similar issues after updating to latest version…
    <div class=”bbp-reply-content”>

    Found that it’s most likely issue with JupiterX-Core plugin – I just reverted Jupiterx-core back to v 1.15.0 and things are working again… (at the moment this link to v 1.15.0 is working: https://downloads.wordpress.org/plugin/jupiterx-core.zip  )

    I hope you’ll fix jupiterx-core asap
    (and please remove latest version of core plugin from update as it’s doing mess)

    hi Louis

    New update of the theme is just released yesterday, it contains fixes for major problems caused by Wp 5.5 and Elementor 3.+version, so it’s a considerable update 🙂
