i have the same problem.
Find the following code in header.php of your Child Theme (around line 9):
<title><?php bp_page_title() ?></title>
And replace it with the following snippet:
<?php if(!bp_is_blog_page()){ ?>
<title><?php bp_page_title() ?></title>
<?php } else { ?>
<title><?php wp_title(”) ?></title>
<?php } ?>
BUT I CAN’T FIND THE CODE <title><?php bp_page_title() ?></title>,who can help?
I think if you created your own child theme and you can’t find the <title> tag then all you have to do is just instert your code above just below the <head> tag
