Re: Custom theme- member profile css issue
Different devs roll out their own WP/BP themes in different ways. In your case, if you made a custom WP theme, did you install the BP Template Pack or did you make it BP-compatible another way?
I have seen a similar problem with an install of BP Template Pack. If you added CSS from bp-template pack via import or added BP-specific CSS at bottom of your WP theme’s style.css, you could add this at the bottom of your active theme’s style.css file. Make sure it’s below all other styles you posted before to make it work.
`div#item-header div#item-header-avatar {
float: left;
height: 150px;
margin-right: 15px;
}
div#item-header div#item-header-content {
float: left;
margin-left: 0px;
}`
Of course, this is just a stab in the dark as you might have had conflicting styling in your theme’s stylesheet which can’t seen via images you posted alone
