Leira Transients is a lightweight, developer-friendly plugin that simplifies the management of WordPress transients.
With Leira Transients, you can: 
– View all registered transients in a single dashboard. 
– Edit transient values and expiration times directly from the admin.
Important: This plugin is intended for users who know what they are doing or have experience in WordPress development. Modifying transient values incorrectly could break your site. Use with caution.
This plugin is ideal for developers, site administrators, and anyone who wants full visibility and control over WordPress’s transient system — no coding required.

This plugin is a Multisite plugin. It can be activated only in network wide. The Surbma | Multisite Transient Cleaner plugin deletes ALL transients from ALL sites in a Multisite. So please be careful and don’t forget to backup your database before acivating this plugin!
The transient deletion only runs once, when the plugin is activated. You can leave it as is, but I strongly recommend to deactivate it and activate again, if you need so.
I don’t recommend this plugin for anybody and I don’t promise anything, this plugin can solve, it is doing, what it says: deletes ALL transients from ALL sites in a Multisite. If you need a simple way to do just this, this plugin will do the job.
