Good morning, I need your help! I have my wordpress and woocommerce website hosted on azure, and when trying to edit a widget I get this error 'invalid JSON...' help!
I already read all the forums with the different solutions, and nothing works. I already installed the classic editor, save the permalinks, it still doesn't work, it only happens with the widgets, and I only have a problem in azure, because I had it in another hosting and it worked perfectly. :/
Edit
link to update your question. Otherwise it seems you already know why the problem happens, it's in the error message. As a result this error message is breaking the JSON data. You should disable all your plugins and switch to a default theme, then re-activate them one by one until the message returns. Then you will know the cause
