What is the problem? Please be detailed.
Aggregate installation on AWS loads simply as a blank screen.
I have been through the DOCs procedure 3 times, and done the install 3 times (even tried a new instance on AWS). Same result. Before trying for a fourth time, I checked the catalina.out log (thanks to a post on the forum for that one!) and found this:

blah...blah...
Caused by: java.lang.UnsupportedClassVersionError: org/opendatakit/common/persistence/engine/mysql/DatastoreImpl : Unsupported major.minor version 52.0 (unable to load class [org.opendatakit.common.persistence.engine.mysql.DatastoreImpl])
I guess my question is, did I cause that with getting some setting wrong during the set up of Aggregate (on my PC) or is there a bug that this has picked up?
Just wondering if I caused the problem with 'datastore' - I've examined my ROOT.war archive, and I can't find the xml file called odk-settings.xml (only odk-settings.xml.example in ROOT.war\WEB-INF\classes) - so I can't check if the mistake is mine...
As it is quite a complex upload process to AWS I don't want to just keep floundering around with trial and error...
What ODK tool and version are you using? And on what device and operating system version?
Aggregate v2.0.1 on Windows 10; installing on AWS Amazon linux
Hoping someone can point me in the right direction...
