When any reports are chosen, Portal just shows "Loading..." indefinitely.
DevTest release 10.0.0 and later.
Cause: (most reason for this issue)
We do not know at this time why these files get corrupted, development is working to resolve, so the resolution is a workaround at this time. This applies to the Registry database being used and can happen with all supported databases.
Shutdown the Registry.
Delete, move or rename DevTest_Home/prodDb.mv.db
Delete, move or rename DevTest_Home/prodDb.trace.db (if present)
You will be able to pull reports now from the Portal.
If these steps do not resolve your issue, please open a support case.
