BuddyPress.org

When I activate this plugin (ae global templates for elementor) my Buddypress pages go white. What can be done?

I created a new buddypress 4.2 site on the latest version of wordpress 5.1 . I have updated all plugins. Notifications does not work, any help on how i can troubleshoot this or is there a plugin i can use for notifications ?

Log:
PHP Warning: reset() expects parameter 1 to be array, boolean given in /site_path/wp-content/plugins/buddypress/bp-core/bp-core-template.php on line 3034

Code: https://buddypress.trac.wordpress.org/browser/trunk/src/bp-core/bp-core-template.php#L3034

Trying to modify a block plugin for my website.

All is going well, but the “block” can be bypassed if the blocked user simply @-mentions the blocker-user. The blocker-user will then receive a notification/email from the “blocked” user.

So I’m trying to catch the notification/email prior to anything being sent. Then I’d compare user IDs and cancel it.

What function(s) should I be looking at?

I found this in bp-activity-notifcations.php but unsure if this is what I’m looking for, unless it is? Is this early enough to prevent the email too?

/**
 * Notify a member when their nicename is mentioned in an activity stream item.
 *
 * Hooked to the 'bp_activity_sent_mention_email' action, we piggy back off the
 * existing email code for now, since it does the heavy lifting for us. In the
 * future when we separate emails from Notifications, this will need its own
 * 'bp_activity_at_name_send_emails' equivalent helper function.
 *
 * @since 1.9.0
 *
 * @param object $activity           Activity object.
 * @param string $subject (not used) Notification subject.
 * @param string $message (not used) Notification message.
 * @param string $content (not used) Notification content.
 * @param int    $receiver_user_id   ID of user receiving notification.

function bp_activity_at_mention_add_notification( $activity, $subject, $message, $content, $receiver_user_id ) {
	bp_notifications_add_notification( array(
			'user_id'           => $receiver_user_id,
			'item_id'           => $activity->id,

Dear,

I noticed I had a problem 2 sites. When i created a Group in buddypress i noticed there was a button rss feeds. I clicked on it and it gave a red page with:
This page contains the following errors on line 6 at column6: XML declaration allowed onley at the start of the document. Below is rendering of the page up the First error.

When I used controle U , I see indeed there is a white space and the code start at the 6th line with
<?xml version=”1.0″ encoding=”UTF-8″?>
I have this problem in 2 of my site. I don’t know how the problem was created. I deactivated all the plugins, I changed my generatepress theme with 2017 theme. I used the plugin: Fix my Feed rss repaire on 1 of my site. When i actived and go to Group –> RSS –> I see somethings new. I some codes with as title: THIS XML file does not appear to have any style information associated wit hit. The document tree is show below.

Searching a bit around i found that it could be that my function.php has a white line problem. I didn’t find any, but to be shure i changed it back to the original.

Does anyone know what went wrong with RSS in buddypress groups and how could i fix this for 2 of my sites?

thank you?
nice day
