Dear Acung,
I was checking this and at our demo site, the URLs for Deep Pockets II 2.0 the URLs are generated fine:
We have following test structure:
1 test category (test category)
2 . L subtest2 (subtest2)
3 . . L sstest (sstest)
4 . . . L level4 (level4)
and the generated URLs are:
localhost/joomla/joomla_test/en/deeppockets/test-category.html
localhost/joomla/joomla_test/en/deeppock...tegory/subtest2.html
localhost/joomla/joomla_test/en/deeppock...subtest2/sstest.html
localhost/joomla/joomla_test/en/deeppock...2/sstest/level4.html
localhost/joomla/joomla_test/en/deeppock...est/newsflash-1.html
...
so I think exactly as expected.
The Deep Pockets version is:
<name>DeepPockets</name>
<author>Aequitas Internet</author>
<creationDate>April 2007</creationDate>
<copyright>Copyright (C) 2005-2007 - Aequitas Internet - All Rights Reserved</copyright>
<license>
www.gnu.org/copyleft/gpl.html GNU/GPL</license>
<authorEmail>info@aequitas-internet.com</authorEmail>
<authorUrl>
www.aequitas-internet.com/</authorUrl>
<version>2.0</version>
so, if you say your version is "2.0b2.1" you may be using some beta, that is not compatible with the extension.
(or the extension is not installed correctly or you have not purged the URL after the extension was installed)
Maybe you can also send screenshot of the JoomSEF extension list
Also please note, in what language your site is published.
As regards Glossary, when checking its non-seo URLs it also seems you are using some different version. Our extension is looking for string like func=display or func=view, while the URLs you have seen are using task=list.
Therefore, in case of Deep Pockets, try using it with 2.0 "stable" and in case of Glossary, you may try with a bit older version.
I assume the other SEO URLs (e.g. for com_content) are working fine for you?
