Frequently Asked Questions

Will this delete my slider images?
The script only removes database entries. You must manually delete the upload directories (instructions included) to remove the actual image files.

Can I undo this?
Only by restoring from backup. The script creates an automatic backup, which you can use to restore your database.

Do I need to uninstall SmartSlider3 first?
It’s recommended to deactivate and uninstall through WordPress first, then run this script to clean up leftover data.

What are Nextend2 tables?
Nextend2 is the framework that SmartSlider3 uses. Tables with nextend2_* prefix are part of SmartSlider3.

Will this affect my posts or pages?
No. It only removes SmartSlider3-specific data. Your posts, pages, and other content are safe.

How much disk space will I save?
Database cleanup saves minimal space. The real savings come from deleting the upload directories (which can be several MB to GB depending on how many sliders you had).

Why can’t the script delete files automatically?
For safety, the script only handles database cleanup. You manually delete upload directories so you can verify what’s being removed.
