tested on my site.
Unable to activate, need to deactivate all my plugins before.
After activation, just run an analyse (no DB change)
then try do deactivate the plugin and then my site crash (too many redirections).
I removed all my plugins and I was able to restart my site.
I re-uploaded all my plugins, except WPDBSpringClean and I got the same error.
I had to recover from a backup :-(
This plugin have to be perfectionned, BACKUP your site before testing !
