Hi Irene,
Welcome to BuddyDev forums.

No, you don’t need to modify that. Instead you can filter the buddyblog form settings and ask it to disply the form for adding meta.

You can filter it like this

add_filter( 'buddyblog_post_form_settings', 'buddydev_custom_buddyblog_settings' );

function buddydev_custom_buddyblog_settings( $settings ) {
	
	$custom_fields = $settings['custom_fields'];
	
	$custom_fields['new_meta_key'] = 	 array(
					'type'    => 'text',
					'label'   => '',
					'default' => ''
				);
	
	//and repeat
	
	//then update settings
	
	$settings['custom_fields'] = $custom_fields;
	
	return $settings;
}

Here is a post that details what meta fields are available

Hope that helps.

Hi Kent,
Welcome to BuddyDev forums.

With the current BuddyBlog, you don’t need to write any custom code for using custom post type. Please visit Settings->BuddyBlog settings and then select your custom post type. Click save. After the page reloads, It will show you taxonomy options for that selected post type. please update as you need.

Hope that helps.

Thank you
Brajes

Please check your bp-custom.php or theme’s functions.php

That redirect can not be caused by bp login redirect plugin. It is before the user is logging in. Some code/plugin is redirecting on account activation.

In that case that plugin will need an update. Which plugin it is, is it bp redirect to profile?
