    Hello @photomaldives,

    The error message you’re seeing indicates that there is a JavaScript issue in the siteground-optimizer-combined-js-1234.js file, specifically at line 185. The error suggests that the script is attempting to call the slice method on an undefined variable.

    What I can recommend in this case would be to check if the Speed Optimizer plugin is up-to-date and if not – make sure to update it. Also, make sure that there are no other caching plugins enabled that may use the same functions/methods and interfere with the proper work of the Speed Optimizer plugin.

    If this does not help – it would be best to post a ticket to our support team from your SiteGround Client Area. This way, they would be able to check the issue in detail.

    Best regards,
    Daniela Ivanova

    thanks, @daniellaivanova

    Yes, the plugin is uptodate, and no, I do not have any other plugins performing caching (to my knowledge).

    I will investigate further and raise a SG ticket if necessary.
