  1. Thanks for your prompt response, Zed! I was just going to update that I fixed it by re-installing the classic widgets plug-in and using that to manipulate / fix my widgets. Still some problems, mainly from custom html generated by Amazon, but working through it. I am trying to go all Guttenberg all the time, but oh well.

  2. I agree. I am struggling with something which I think is Block Editor related. I can’t effectively manage some of the custom html widgets. I get an error of “There was an error. The response is not a valid JSON response.” when I try to delete a widget. I love Mantra and want to keep using it. is my site. Thanks.

  3. I’ve been using Mantra for years and it’s a beautiful, fast theme. Sure, I’ve tried others for a few hours, just to see, but I always return to Mantra. It’s simple and speedy, and that’s what Google likes and that’s what my visitors like, too.
