Having the exact same issue. Deactivating the widget lets me crop BuddyPress profile pictures.
Difference in code when plugin activated and deactivate are:
<script type="text/javascript" src="https://www.globalchangeawareness.eu/wp-content/plugins/q2w3-fixed-widget/js/q2w3-fixed-widget.min.js?ver=4.0.6"></script>
<script type="text/javascript">
jQuery(document).ready(function(){
var q2w3_sidebar_1_options = { "sidebar" : "primary", "margin_top" : 95, "margin_bottom" : 650, "screen_max_width" : 0, "width_inherit" : false, "widgets" : ['alxtabs-2'] };
q2w3_sidebar(q2w3_sidebar_1_options);
setInterval(function () { q2w3_sidebar(q2w3_sidebar_1_options); }, 1500);
var q2w3_sidebar_2_options = { "sidebar" : "secondary", "margin_top" : 95, "margin_bottom" : 650, "screen_max_width" : 0, "width_inherit" : false, "widgets" : ['bp_core_recently_active_widget-2','text-8'] };
q2w3_sidebar(q2w3_sidebar_2_options);
setInterval(function () { q2w3_sidebar(q2w3_sidebar_2_options); }, 1500);
});
</script>
Obvious enough as that code is injected by the fixed widget plugin.
Plugin Activated
Plugin Deactivated
Getting no errors or warnings about anything to do with either BuddyPress or Q2W3 Fixed Widget.
Fiddled around a bit, changed “resize” in .js and .min.js to “resized” at all occurrences just to see if that was it, but it wasn’t ??
