I have a real problem here. IntelliJ seems to have lost my local history.
Initially my problem was that although the various versions of the file in the "differences" window (Version Control > Local History > Show History) were showing in the bottom pane, both left and right versions of the file were shown as "File content is not available (read-only)".
Quitting and relaunching IntelliJ seems to have made the history work again...but only from that point on! i.e. I seem to have lost the history for my entire project.
Is there any way I can get my history back?
This has suddenly happened in the past few days, and I have not changed anything in my project setup since the last time it worked.
