oh thank you @optimizingmatters !! the issue is based on the domain missing in the image URL and when i include the domain name to URL it works perfectly.
Thank you for the solution!! <3
i dont have any domain-removing plugin!!. i have 2 plugins named “Custom Permalinks” & “Redirection” and which is used for to Set the URL of any post, page, tag or category to anything you want & the redirection of a particular page.
