Happy New Year!
Thank you very much for your help Kharis, but I did not resolved it. The “0” I would like to replace is betwen the tags (in posts, such as http://www.petkovstudio.com/timeline/, in red circle).
So, I would like to find this “0” in code and to replace it with bullet. You can brouse the code in https://themes.trac.wordpress.org/browser/sydney#1.43/post-templates
Thank you very much in advance!
I have another question - why the designers of Sydney Theme desided to change the most beautiful thing - the icons of the autor and the date of the post
as it is in home page http://www.petkovstudio.com
or in Sydney Demo page http://demo.athemes.com/themes/?theme=Sydney
Can I ask the designers of the theme to return the icons in posts?
Thank you very much.
