Hi stblink,

good debugging work - well done.

1 - the reason you are getting a duplicate of the module is that the MetaMod can't prevent the "target" module (263) showing up, if it's assigned to a valid page(s) and/or module position(s). All MetaMod can do is to show something on the page, not remove something that's already there. [actually with the Pro version you can do that, but that's a different matter].

So, I'd suggest that you take the target module and assign it to "none" module positions. Then it will only show up when MetaMod includes it.

2 - the module class suffix. This is a trickier situation, and if all else fails you may need to "go Pro" in order to get it working properly.
The issue is that without Pro, you have 2 lots of HTML appearing. There's the basic MetaMod module's HTML "wrapper", then inside that you have the module that it's including.
Now on every page where the MetaMod is assigned, you're going to get that "wrapper" HTML. But only on the login page is the MetaMod going to decide to include the target module.

So every page is going to have some HTML, and the login page is going to have nested HTML.

Sometimes it works to put the module class suffix in the MetaMod. But this may cause the MetaMod itself to be styled (background color etc), and that may not look very good if the MetaMod is empty.

Therefore I recommend that you put in a "fake" class suffix for the MetaMod, eg. "-fake". Often this is enough to make the CSS rules disregard styling the outer MetaMod, and hopefulyl still style the included module, but that really depends on the exact html/css in your template.

Then, I would try the different styling options in MetaMod to include the inner module. The best bet is to examine your template's index.php file and see if there was a style specified for the module position that it's in. e.g.:

<jdoc:include type="modules" name="position-7" style="beezDivision" headerLevel="3" />

If you get a "style" parameter like this, you should enter this into the "style override" box in MetaMod. If instead you had a line like this for the module position:

<jdoc:include type="modules" name="left" style="rounded" />

... then you can use the dropdown in MetaMod to select "Multiple divs (for rounded corners)". In fact I'd try all the different options in that dropdown to see if there's one that works properly.

So the options again:
a - set a fake class suffix in the MetaMod
b - and try different options for the "Style for included modules" or "Style override for included modules"
c - and set/keep the module class suffix in the target module

OR
d - get MetaMod Pro. MetaMod Pro completely removes the HTML "wrapper" that the MetaMod module would normally have added around the target module. This means that the empty MetaMod module does not show up at all on pages where it does not include any other modules. And, when it does cause a module or modules to appear on a page, there's no additional HTML surrounding them.

Best regards,
Stephen
