 * Hi all,
 * For some reason all site that have wordpress widgets blocks, started givin a 
   error of “the response is not a valid JSON response”, every time i try to save
   theem, that problem doesnt happen in Personalize. ALreadry tried the permanent
   links solution and nothing. The strange thing is that only happens in the Widget
   configuration. I noticed this in all site that have wordpress 5.8.
 * And yes i alreqady truyed the plugin classic widget, it worked but a new plugin
   in int not a solution for now, because i will happen to new sites also.
 * i have IIS and php 7.3

 * > the response is not a valid JSON response
 * – a plugin conflict either 1) a plugin doing something that creates output, thus
   breaking the response or 2) a plugin doing something with caching),
    – an overloaded
   server, – misconfigured http/https address in General Settings, – permalinks 
   may need resetting, – theme/plugin conflict, – check Site Health: From your WordPress
   dashboard, if you go to Tools and then select Site Health, then under the Status
   tab on that page, WordPress will show you any improvement recommendations that
   could help your website. An issue related to Rest API could also cause the JSON
   response error on your website. Moreover, if you find any issue there, solving
   the issue might also fix the JSON response error for your website, etc.

 * I am the server, :P, and the problem only happens with the wordpress version 
   5.8 and above sites, the ones that are still down that version or dont have block
   dont have that problem. Also only happens in the widget menu. not anyplace.
