Hello,
this module does not want to send any notifications to the mailbox.
I have PS 1.7.6.0
Is any additional module configuration required?
Where can I find the window with information about alerts (screenshot in the attached file)
You need to translate email templates to your language(s). Also, note that this module reacts on changes to base price only. If you change price by using specific price or cart rule, it will not be detected.
Regarding alert list -- as written on product page description, module itself doesn’t have any functionality to export price alert data, but it is integrated with DataKick module - your price alerts data will be available for creating lists, xml exports, inline editing and mass updates just as any regular record type.
