TITLE

WordPress Toolkit: unable to restore a backup when table prefix is changed via Security Measures

PRODUCT, VERSION, OPERATING SYSTEM, ARCHITECTURE

CentOS Linux 7.9.2009 (Core)
Product Plesk Obsidian Version 18.0.41 Update #1

WordPress Toolkit
Version 5.9.3-6032

PROBLEM DESCRIPTION

When you start managing an existing WP website in WP Toolkit, you run into issues when you create a backup using the WP Toolkit and next apply the security measures like "Change default database table prefix".
If you want to restore the backup, it seems to be impossible:
"Failed to restore site from backup

• Error: The site you have requested is not installed.
• Your table prefix is 'wp_'. Found installation with table prefix: xxxxx_."

This is odd, as the info icon next to "Change default database table prefix" warns you to create a backup before you apply the security measures:
"Note that changing database prefix on a website with production data might be dangerous, so it is strongly advised to back up your website before applying this measure."

STEPS TO REPRODUCE

- Scan for an existing WP website using the WP Toolkit (check if it uses the wp_ prefix in the database)
- Create a backup using the WP Toolkit
- Apply the security measure "Change default database table prefix"
- Try to restore the backup using the WP Toolkit

ACTUAL RESULT

You get an error and the website is broken:

"Failed to restore site from backup

• Error: The site you have requested is not installed.
• Your table prefix is 'wp_'. Found installation with table prefix: xxxxx_."

EXPECTED RESULT

The expected result is that the backup is restored.
