The traceback is below, since I don't speak python it doesn't mean much to me. The list works, but the error below appears when anyone enters their email address and tries to see their subscrition options.

I would be grateful if someone could give me some pointers as to what I have done wrong.

Many thanks.

Someone has (hopefully in mm_cfg.py, but possibly by editing Defaults.py) redefined LC_DESCRIPTIONS as a list instead of a dictionary.

Actually, wouldn't 'lang' be the culprit here, as that is what is not hashable? If LC_DESCRIPTIONS was a list, the error would be:

AttributeError: 'list' object has no attribute 'has_key'

...

...

d = {} d.has_key([1,2,3]) Traceback (most recent call last): File "<input>", line 1, in <module> TypeError: unhashable type: 'list' x = [] x.has_key Traceback (most recent call last): File "<input>", line 1, in <module> AttributeError: 'list' object has no attribute 'has_key'

If you don't know how to fix this, post your mm_cfg.py, and, if you've made changes to Defaults.py, see the FAQ at <http://wiki.list.org/x/fIA9> and post those too.

Note that in any case, if you have something like

LC_DESCRIPTIONS = []

in mm_cfg.py, that is wrong on two counts. LC_DESCRIPTIONS is a dictionary and an empty dictionary is {}, not [], and if LC_DESCRIPTIONS is redefined in mm_cfg.py, add_language() will still update the original dictionary.

The correct thing to put in mm_cfg.py for Mailman 2.1.9 if you want say English as the only language is

LC_DESCRIPTIONS.clear() add_language('en', 'English (USA)', 'us-ascii')

I suspect this error occurs because somehow this list's language has been set to a list of languages rather than a single language.

If you view the source of the list's listinfo page, you should see near the end something like

...

<INPUT name="UserOptions" type="SUBMIT" value="Unsubscribe or edit

<FORM Method=POST ACTION="../options/LISTNAME"> To unsubscribe from LISTNAME, get a password reminder, or change your subscription options enter your subscription email address: <p><center> <INPUT name="email" type="TEXT" value="" size="30" options" ><INPUT name="language" type="HIDDEN" value="en" ></center> If you leave the field blank, you will be prompted for your email address </FORM>

What is the value in the <INPUT name="language" type="HIDDEN" value= > element?

Ah, that gave me the clue to find it ....

The form at the bottom of the page had become 2 overlapping forms, so looking at (near the bottom):

/listinfo.html

I saw:

  <TD COLSPAN="2" WIDTH="100%">
<MM-Options-Form-Start>
<MM-Editing-Options>
     <p>
<MM-Roster-Form-Start>
<MM-Roster-Option>
<MM-Form-End>
<p>
<MM-Form-End>
  </td>

Once I fixed it to:

  <TD COLSPAN="2" WIDTH="100%">
<MM-Options-Form-Start>
<MM-Editing-Options>
<MM-Form-End>
    <p>
<MM-Roster-Form-Start>
<MM-Roster-Option>
<MM-Form-End>
  </td>

It all worked.

So the problem was that there were 2 elements called 'language' in the form. Many thanks for the clue.
