Project not opening: Console says "Loaded project" but wheel still spinning on browser

[Matriim]

Hi all,

I have been working on this project for a few weeks now and this morning after starting a transpose operation the project seems to be stuck on "working". So I tried refreshing. The page was just blank so I checked the console and it said that the project had been saved. So I decided to close down everything and restart. Now my project wont open at all (see screenshot).

Is there a way I can recover or do anything to retrieve the project as it was before this morning?

Hello again. Jyst wanted to say that I managed to solve this. Before doing anything I made a backup of the entire openrefine folder in windows inside username/roaming/openrefine. Once I had a copy of the folder and made sure that my project was in there as well I proceeded to try several things. The one thing that worked was to increase ram availability in the fonfiguration file. I managed to finally open my project like this, but found out that I couldnt undo changes as I was getting error "java.lang.NullPointerException". So I exported my project. Deleted the project in openrefine in the browser and then reimported my project. Now all is working well and I can undo changes and everything.
