Fix non-friendly URL issue - Joomla

[login to view URL] Currently SEF Friendly URLs are not enabled. .htaccess is present. So, obviously, at this time, SEF Friendly URLs do NOT show. If I enable SEF Friendly, most URLs work correctly. However, category blog URLs do not. For instance [login to view URL] is Home | OUTDOOR & ADVENTURE | BEACHES. However, if you click one of the read mores the URLs revert to SEF Friendly. However, there's another issue. If SEF Friendly are enabled, once you click a read more all images outside of the main content area disappear (for example, in the header). On checking the path, instead of being images/[login to view URL] (for the Facebook icon in the top bar) the categories get inserted into the path so it becomes outdoor-adventure/beaches/images/fb.png. I believe they will be related, but I just can't figure out where the problem is. I used a component called Form2Content Lite so that my client could enter the articles and have them all appear on a consistent layout. It has worked well for this. What hasn't worked so well at times - causing layout issues at category blog view, is him inserting a bunch of inline styling without really knowing what he's doing. Plus, initially, copying and pasting from Word or other websites directly. Had to do some major code deleting a few times because of that. However, I don't know if that's necessarily the issue. Seems more likely it's somewhere in the categories.
