TypeError: Cannot read property ‘MediaFrame’ of undefined

  • WordPress version 5.4.1

    I get this error when trying to edit a page. I don’t think it’s plugin related since there are no plugins cited in the trace below.

  • I am having the same issue with the same error message. I even restored my backup to see if it was to do with a plugin update but it didn’t fix it.

    Hi @joshmacd – I tried opening my dashboard in another browser and didn’t get the errors. So I still get the errors if I open it in chrome but not in safari. Hope that works for you too!
