We have a long running study, which has run into same 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 header bar or the 404 Error screen depending on the brower. 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 184.108.40.206
Can anyone help please?
