Never really noticed but I have somehow never gotten my RSS functions to work when using OpenSef.
Is there a general conflict between the Joomla RSS feed system and search engine friendly urls?
In case you know something about all this - please share!
I use RSS feeds together with OpenSEF. What exactly is the problem you are having?
On my site, the syndication module outputs feeds that contain friendly URLs all right. There was an issue though with the live bookmarks - for some reason, the Live Bookmark URL wasn't rewritten, which in turn led to Technorati picking up my articles with the old /content/view/blah/blah URLs. I had to hack includes/frontend.php to resolve that issue.
