You can enable logging which is described in the wiki: https://github.com/textmate/textmate/wiki/Enable-LoggingBut that has to be done before starting textmate, so the question remains if you can reproduce the problem after a restart?
The times I had this error was when a file was not writable (mostly on network drives) or the file was non-existing.
Using TM2 release 9497
When I attempt to save a file (demo.php) TM2 reports that it is Unable
to save file. Check console for details.
When I look in Console, I didn't find an entry from this date from
Textmate. Where, specifically, should I look for what is happening? The
file itself can be replaced, but it would be nice to understand what's
happening. Can anyone explain?
