Hello Oleg,
Sorry for the late response as it's a holiday here.
1) Doubled slashes in urls that you have pointed to in XML sitemap
I had fix this issue for you.
2) HTML sitemap links now are not SEF urls (links were SEFed, but with trailing Itemid-s after "html" suffix)
I'm sorry but i could not find the trailing numbers on your URL
Can you also remove word "entry" from urls because it is absolutely unnecessary?
you could not remove this because Joomla uses it to generate the views for the page.
I had change the routing behavior so it will not follow the current menu-item
Backend > EasyBlog > Settings > SEO > Advance to Default.
To make better SEF URL you might have to use SEF extension so you could have better control over it.
Also it would be nice if my site breadcrumbs are built logically:
Breadcrumbs will follow if your menu-item if available. In this case there is no category menu-item.
And finally please put back changes in global configuration
Do you mean the SEO settings? I did not change the settings because I was unable to save the settings there, please advice.
Thanks:)
