We have a long running study, which has run into some problems today. Whilst carrying out data entry the users have discovered they can no longer add discrepancy notes to a field by clicking on the blue flag beside the varible - a blank screen appears with just the blue header bar or the 404 Error screen. Up until today, all was working well. All other studies we have are working fine, it just seems to be this one that is affected.
it is running on version 22.214.171.124
Can anyone help please?
