This is a bit confusing, but let me try to explain. Note I even confused myself, the previous "fix" should not be used.
- In 1.1.8 you either allowed or not, nested quotes. It was simply yes or no.
- In 1.1.9 this changed to a value. 0 is intended to not allow any nested quotes (same as checking "Remove nested quotes when quoting" in 1.1.8) and any positive number will allow that many nested quotes inside of your quote.
Ruth, the issue you reported is working as expected. You had a message that was only a quote, nothing more. Quoting that but not allowing nested quotes means the quote is stripped and there is nothing left to quote. (my "fix" made that worse)
Lets try some examples, here is a topic thread.
1) message
2) <quote>message</quote>
first response
3) <quote><quote>message</quote>first response</quote>
second response
4) <quote><quote><quote>message</quote>first response</quote>second response</quote>
third response
Setting Allowed nested quoting depth to zero means all quotes are removed and only the text added by the quoted message will be used. You are quoting just the text of the reply.
Examples
quoting number 4 above would give:
<quote>third response</quote>
your response here
quote number 2 would give
<quote>first response</quote>
your response here
Setting Allowed nested quoting depth to 1, a single quote nested inside of your quote (the outer most) will remain
Examples
quoting number 4 above would give:
<quote>
<quote=1st nested quote>second response</quote>
third response
</quote>
your response here
quoting number 2 would give
<quote>
<quote=1st nested quote>message</quote>
first response
</quote>
your response here
Setting Allowed nested quoting depth to 2, two nested quotes inside of your quote, are allowed
Example
quoting number 4 above would give:
<quote>
<quote=1st nested quote>
<quote=2nd nested quote>first response</quote>
second response
</quote>
third response
</quote>

In working on this there is an inherited issue when removing nested quotes on a message that had nested quotes. An example is a message with several quotes like this <quote><quote>message</quote>first quote</quote>second quote would become <quote>message first quote second quote</quote> So indeed it strips all the quotes, but jumbles the text of the various quotes into one.
One primary reasons for changing to a depth level was to allow for a quote in a post, so for example a message like
I would like to quote someone who said <quote>spuds is mental</quote> and agree with them
... if you do not allow nested quotes, this becomes <quote>I would like to quote someone who said and agree with them</quote>
when quoted and that breaks the flow. In 2.0 I've considered adding some indicator that the text was quoted using the quote button vs the editor quote button so the system could be more intelligent about what its removing. That said it is already rather confusing.
