Support » Plugin: ShortPixel Image Optimizer » short-pixel.min.js error

  • Resolved ro78727


    In troubleshooting a different plugin problem, their tech support noted that shortpixel is throwing errors.

    I was on WP 4.9.8 when these problems started. I’m now on 4.9.9.

    Error below:

    short-pixel.min.js:1 Uncaught TypeError: Cannot read property ‘toLowerCase’ of undefined

    thank you for your message, sorry to hear about this issue.

    We believe the problem is caused by your WP using an older version of the javascript files.
    Could you please empty your browsers’ cache and also flush any cache your website may have?
    This should solve the issue noted by you.

    I would appreciate your follow-up on this.

    Thank you,
