Hey Michael,
Why is this simple issue so difficult for you to resolve? Your question, "May I know, where do you publish your blog post as you mention above where the email notification URL is different?" has been answered above.
We tested in our locally regarding this 3.x latest version, it seems work fine, you can refer on my attached screenshot below. I would love to help you to solve this issue quickly if you can provide us with your Joomla backend and FTP access so we can directly look into this issue.
Because there have a lots of possibility causing this issue :
1. Installed 3rd party SEF extension
2. Some of the plugin conflict it
3. Easyblog 3.x might not compatible with some of the Joomla version (I think 3.4 onward)
4. Menu structure conflict
What is sh404sef?
This is one of the SEF extension for build your site URL user-friendly.
We would prefer not to provide back-end access to our site at this time.
What do think the root cause is? Please provide specific questions regarding our configuration that I may answer.
Hm, May i know what is the reason you not prefer to provide us with your Joomla backend and FTP access? Perhaps you have something else need to take care about? It would be best if you can share with us so that we can provide you some suggestion regarding this, because we really need to access your JOomla backend and FTP so that we can troubleshoot this issue, I hope you can understand.
