Groups Plugin has broken links if it has a colon :

In the Groups plugin on Elgg 1.7.1 which I just installed there are the links to Group Blogs, Group Bookmarks, Group Files, and Group Pages on the left hand sidebar under Group Discussion. The Group Discussion link works but the others do not, the difference is in how the links are structured.

The Discussions link has this structure: /pg/groups/forum/{GroupIDNumber}/

But the Blog link has this structure: /pg/blog/group:{GroupIDNumber}

Here's the link structure for the rest of the broken links:

Bookmarks - /pg/bookmarks/group:{GroupIDNumber}/items

Files -/pg/file/group:{GroupIDNumber}

Pages -/pg/pages/owned/group:{GroupIDNumber}

The difference in the broken links and the one that works is the use of the colon and the group ID number and how it's placed in the structure, so this tells me that the issue is most likely one of the .htaccess not having the correct rewrite rule in place for this page handler rewrite, I checked the .htaccess that came with my install and it only has the two page handler rewrites that don't have any colon in the regular expressions to match.

Also I checked under the groups folder in the mod section and there isn't any php files for blog or bookmarks or any of the links that don't work but there is a php file for forum which is the one that works.

So if someone can let me know how to fix this I'd appreciate it, thanks.
