In the past few months, we have received many requests for help on the issue related to the WordPress Media Library.

Instead, they were getting only greyed-out and blank document icons in the media library.
General initial troubleshooting steps
Before trying any other solution, you must need start a quick version-check and plugin testing process. Start by making sure all your files are up-to-date, and that your WordPress website is currently running the latest version of WordPress and all the active WordPress plugins.
It is important to use the most recent version of WordPress core files. You need updating your WordPress to the latest core version should resolve those issues.
Please follow the good way to update file – Make a full backup of your WordPress website files including your database, then update your original files first and your plugin. Check to see if thumbnails are displayed properly after updating files. Assuming that your files do not help updating, or your files were already running latest version, go to plugin testing.
Start to deactivating all your plugins, then check your thumbnails. If the problem is resolved, then your problem is one of the plugins that you have just disabled. Try to reactivate them once in a while, check the media library in between the middle of reactivating, unless you indicate which plugin is causing the problem.
If it is a simple matter to deactivate and delete that particular WordPress plugin, and if necessary find a practical alternative plugin. However, this process does not reveal the potential culprit, then now it is time to go to more specific solutions as given below.

If it is anything other than 755 (or 777, although it can present security risks), change permissions. Go back to your settings => media page in your WordPress dashboard, and then uncheck my uploads in the month-and-year-based folder option. Check back to see if the thumbnail is loading now or not.
