    From 90/100 score in speedtest software I am now at 40%, without any significant change. I check server’s log files and I see too many warning:

    “mod_fcgid: stderr: PHP Warning: Attempt to read property “post_title” on null in “…/wp-content/plugins/js_composer/include/helpers/helpers.php on line 60″”

    I am not sure if this is the only thing that affects website speed, but it is something I need to check.

    Thank you in advance

    Thank you for your prompt response. I have done my research and I started to improve things on the website. However, I face the following issue: I have 4433 php deprecated warnings and 4371 coming from js_composer which is WP Bakery’s file. I see WP Bakery offers an update but since I have WP Bakery through the theme I cannot update it. Could you provide me with the updated version.

    Hello, @george kakamoukas,

    Thank you for reaching out, and We appreciate your proactive approach to improving the website. We understand the challenges you’re facing with the PHP deprecated warnings and those originating from js_composer in WP Bakery.

    1) Regarding the WPBakery update, since it is bundled with the theme, you’ll need to update the theme itself to get the latest version of WP Bakery. Please follow the instructions outlined in the XStore Article on updating theme included plugins: and -This guide will assist you in updating the necessary components, including WP Bakery.

    2) Now, regarding the PHP deprecated warnings, it’s important to note that these warnings often occur when the website is in debug mode. To address this, I recommend turning off the debug mode. The warnings are not visible in the production environment, and it helps maintain a cleaner codebase.

    For detailed instructions on turning off the debug mode, please refer to the official WordPress documentation on debugging: .

    Feel free to reach out if you have any further questions or if you encounter any issues during the update process. I’m here to assist you.

    Best Regards,
    8Theme’s Team.
