Do you have any idea what this can be and if the registrations can be recovered?
I can see on WordPress some things need updating because of this error message… do you think this is the cause also I see I need to update the PHP.
Which error message?
From the above it sounds like the registration have been removed from the database, however, EE can’t delete registration with related data (in short once you pass the ‘attendee information’ step, there’s related data) and if they aren’t in the database you can’t recover them unless you have a back that still has them in it.
First, what dates are missing? Are they recent?
Has your host done any kind of maintenance, or ‘database optimizations’ recently?
Ever had the site cleaned after an infection/malware?
