Problem in easyblog after upgrading easyblog

Hi

1. The sub categories on the website are not opening up. Because of this all the new articles that we are posting have to be attached to the main category + the sub category in order for them to appear on the website
For example https://magazine.esra.org.il/posts/entry/a-tribute-to-the-queen.html is in the sub category Music and because I didn’t attach it to Art and Culture you can’t see it in the top category and because the sub categories aren’t listed you can’t find the Music category…
On the mobile site all the categories and sub categories are open are open.

2. The captions of the Post Cover are not displaying properly. They appear on the category page on top of the picture and on the article page at the side of the picture. For example
https://magazine.esra.org.il/posts/entry/escape-from-ukraine.html
(category page (https://magazine.esra.org.il/posts/categories/jewish-scene.html)
https://magazine.esra.org.il/posts/entry/teens-have-rights.html
(category page https://magazine.esra.org.il/posts/categories/education.html)

3. How can we modify the article page. We need to display the author name in a new page..

4. Most of the articles (not all!!) have a blue shadow behind the text, particularly at the beginning and at the end of the article for example
https://magazine.esra.org.il/posts/entry/escape-from-ukraine.html

5. Stay Informed should be one long line. Where does the Stay Informed button lead to?

please advice
