The debug notice is telling you there’s a non-static method called get_by_parent() which belongs to class BP_Groups_Hierarchy. Somewhere in your site, the method is being called statically like this BP_Groups_Hierarchy::get_by_parent(). You can’t do that in PHP as only static methods can be called in this way.
Looking at the debug message, that somewhere in your site is: wp-content/plugins/bp-group-hierarchy/bp-group-hierarchy-functions.php on line 35. So it looks as though you might need to contact the BP Group Hierarchy plugin author making them aware of the issue.
There’s likely a plugin, theme or custom code snippet you have installed still using the deprecated function bp_core_delete_notifications_by_type(). The notice is telling you to use bp_notifications_delete_notifications_by_type() instead.
There’s no right and wrong way but this is what I do:
Put all of your global CSS properties into style.css. for example, styles that related to your header, footer and main templates and then conditionally enqueue stylesheets that are used less regularly so that they’re only loaded when absolutely necessary.
@jay_chauhan when there’s a problem like this, it’s quite difficult to know where to look first because the problem is so broad. The link @bphelp provides above is a good place to start.
The usual approach is to disable all plugins, use the Twenty Fifteen theme, remove all custom code in functions.php and bp-custom.php and then work forward from there to identify what is introducing the problem.
Yes definitely, but going on the info you’ve provided so far, I have no idea how. You’ll need to provide a lot more info; your setup, any custom code you’re using and so on.
Look into using the bp_after_has_members_parse_args filter. I think it’ll let you override the meta_key and meta_value params. That may help you do what you want?
I don’t think there’s any reason why these shouldn’t have ajax functionality. It may well be planned, but I’m not sure? Take a look through the open Trac tickets to see if anything is in the pipeline.
Try adding a default case to your switch statement like I’ve shown above. Then check in the wp_users table in your database to see what role is assigned.
I’ve had problems when using is_page() in BuddyPress in the past. In addition to that conditional, try putting in further checks such as bp_is_groups() or bp_is_friends() (or whatever is relevant to your task).
