Please let us know if you keep seeing the error more than once.

so that we can figure out what exactly is going wrong.
Since I reported the first warning message in this thread, I've had about half a dozen similar (but not identical) ones when opening an org file. They are not repeatable though, in the sense that if I close the file and re-open it I don't see the warning a second time.
The latest message is this:
Warning (org-element-cache): org-element--cache: Org parser error
in file.org::1687. Resetting.
The error was: (error "Invalid search bound (wrong side of point)")
Backtrace:
nil
Please report this to Org mode mailing list (M-x
org-submit-bug-report). Disable showing Disable logging
