Support » Plugin: Slider, Gallery, and Carousel by MetaSlider - Responsive WordPress Plugin » Cannot read property “toString” of undefined

  • This message appears when click on: Export in Settings & Help in MetaSlider Admin area.
    After a few moments the message: “All Slideshows loaded” comes up.

    Wordpress Multisite: 5.7.2
    MetaSlider: v3.20.3

    I have also activated: “jquery migrate helper plugin”, but that does not change anything here.

    Thanks for the reply

    Thank you very much for these detailed steps. I’ve reported the issue to the development team so that they check it.

    Please keep watching this ticket and I will notify you once I get any updates.




    Good afternoon, I have the same error, also that I cannot edit any slider.
