Featured images are not loaded when I open a post in editor -> February 2, 2022 at 1:39 am #2102336 Fernando Customer Support Hi Prakshah, This is not a theme related issue. Can you try rebuilding the Permalink structure of your website? To do this, you’ll need to go to Settings > Permalinks > Save Changes. See this for reference: https://share.getcloudapp.com/yAukAJEe You only need to click “Save Changes” and this will automatically rebuild your Permalinks. Moreover, some steps you may also try to resolve this issue can be found in this link: https://passionwp.com/response-is-not-a-valid-json-response-error/ Hope this helps! 🙂 Author Posts Viewing 2 posts - 1 through 2 (of 2 total) You must be logged in to reply to this topic.
