Which titles:

1) Clickable:

This is a title

or

2) With links in the names:

This is a title httр://site.com

?

For example, the title of the blog post can be made into a website link

I can't reproduce it on Elgg 3.

Perhaps, the 3rd party plugins are being used.

Can you post an example of title?

I can not include links in the title of my blogs (Elgg 3.3.10).

I think your website is full of spammers (46k users). Install the Spam Login Filter plugging that works great.

Wogker Do you suggest any addition?

Of couse, You can writre an url in the blog title but never as an active link. I do not understand the problem.

addition = recomended plugins?
