I had a problem where my events table had got really big so I couldn't log in (it kept timing out). Using the H2 Console I was able to delete everything from the events table but now I have no custom pages or menu structure.
If I edit the latest json backup, it looks like the menu structure is there but I get nothing except for Data Point Details, Events, Watch lists and the Administration section, even after re-importing the json file.
I also don't see any errors in the ma.log except for a server key validation issue regarding CloudConnect.
Any help would be greatly appreciated.
