I'm having the very same problem and am totally at a loss here. Looking forward to this answer!

I tried this but am still getting the -2 and -3 endings on a freshly installed 2.2.5 version and cleaned url cache.

I have my homepage set to the joomla frontpage component and have looked everywhere. My homepage actually has \"homepage\" in the title (which shows up in Search Engine Results and is quite unappealing). Where do I go to edit this? All the other pages, blog posts, etc, don't have the Page Title (which is fine with me.)

Thanks

I have the exact same request/issue and can't seem to work it out. Can anybody help?
