Scenario:
- Images are not showing in images.
- But the path to the images via WP are correct.
- Database path as well are correct.
- Changing the theme does not help fix the issue.
- Disabling all the plugin does not help as well in fixing the issue.
- Upgrading the PHP was of not use.
- Upgrading WP core and WP plugins are not much of help.
For some reasons I could not understand yet:
- Activating Jetpack and enabling the features under Performance & Speed in Jetpack resolved the issue.
