Transients can be incredibly useful, but sometimes things can go wrong.
For example, if the connection between Facebook and your WordPress website isn’t working, it will show a post share count of 0.
Instead of waiting for the transient to expire, you can simply clear the transient cache to get the correct share count instantly.
If you are experiencing an issue with your popular posts or share counts showing up, and you’ve cleared your WordPress cache, then it could be an issue with your transients.
Clearing out expired transients can also help to optimize your WordPress database and give you better performance. This can be helpful when you are moving a staging site to a live WordPress hosting server.
