Images on Posts and Text Block Elements Broken
If you are having broken images issue when trying to add media, especially jpeg and png images, on blog posts and text blocks on Live Editor pages, re-install your WordPress from the dashboard. Go to Dashboard >> Updates >> click reinstall now.
In case the issue would persist, please reach out to your web host and have them re-install WordPress at the back end as this issue is normally caused by missing or corrupted WordPress installation.
We also have found a few cases recently on certain web hosting companies deleting these core WordPress files; thus reinstalling WordPress is needed to fix the issue.
