Hey there,
I am really sorry for the delay of this reply as it is a weekend for us here.
I have following issue:
each blog category link doesn't work (404 page not found)
I have last version of Joomla/EasyBlog
Local installation : it means I cannot provide you any access to the website
Can you help me?
Hm, that was very hard for us to know what is the issue causing this by looking on your screenshot. It would be best if you can upload your local site to live temporary so that we can directly access and troubleshoot on this.
I have also seen that also the Author profile link doesn't work
the wrong links point to index.php/component/easyblog/blogger/pcvueblog?Itemid=126
By the way, I've take a look of your screenshot, can you try follow my instruction and see is it help?
If no, I would strongly recommended you temporary upload your local site to live.
1. Can you check what is this item id 126 from backend > Menus ?
2. Double check this from backend > Easyblog > setting > seo > advanced tab > set to `default`
3. If you do not want to show your Easyblog frontpage menu item on your menu bar, you have to create a hidden menu > add new menu item for `Easyblog frontpage layout`
