Hi,
My apologies for the delayed reply. I had to install OcenWp to see if the include custom js for BuddyPress or not.

Please copy the plugins/buddypress/bp-templates/bp-legacy/buddypress/js/buddypress.js to your theme/buddyoress/js/buddypress.js and look for the code which looks like this

		/* Load more updates at the end of the page */
		if ( target.parent().hasClass('load-more') ) {
			if ( bp_ajax_request ) {
				bp_ajax_request.abort();
			}

			jq('#buddypress li.load-more').addClass('loading');

			oldest_page = activity_oldestpage + 1;
			just_posted = [];

			jq('.activity-list li.just-posted').each( function(){
				just_posted.push( jq(this).attr('id').replace( 'activity-','' ) );
			});

			load_more_args = {
				action: 'activity_get_older_updates',
				'cookie': bp_get_cookies(),
				'page': oldest_page,
				'exclude_just_posted': just_posted.join(',')
			};

			load_more_search = bp_get_querystring('s');

			if ( load_more_search ) {
				load_more_args.search_terms = load_more_search;
			}

			bp_ajax_request = jq.post( ajaxurl, load_more_args,
			function(response)
			{
				jq('#buddypress li.load-more').removeClass('loading');
				activity_oldestpage = oldest_page;
				jq('#buddypress ul.activity-list').append(response.contents);

				target.parent().hide();
			}, 'json' );

			return false;
		}

It is around line 431, we need to add 1 line

MathJax.typeset();

as shown below.

		/* Load more updates at the end of the page */
		if ( target.parent().hasClass('load-more') ) {
			if ( bp_ajax_request ) {
				bp_ajax_request.abort();
			}

			jq('#buddypress li.load-more').addClass('loading');

			oldest_page = activity_oldestpage + 1;
			just_posted = [];

			jq('.activity-list li.just-posted').each( function(){
				just_posted.push( jq(this).attr('id').replace( 'activity-','' ) );
			});

			load_more_args = {
				action: 'activity_get_older_updates',
				'cookie': bp_get_cookies(),
				'page': oldest_page,
				'exclude_just_posted': just_posted.join(',')
			};

			load_more_search = bp_get_querystring('s');

			if ( load_more_search ) {
				load_more_args.search_terms = load_more_search;
			}

			bp_ajax_request = jq.post( ajaxurl, load_more_args,
			function(response)
			{
				jq('#buddypress li.load-more').removeClass('loading');
				activity_oldestpage = oldest_page;
				jq('#buddypress ul.activity-list').append(response.contents);

				target.parent().hide();
                               // New line added. 
                               MathJax.typeset();
			}, 'json' );

			return false;
		}

You will need to rename the file to buddypress.min.js (or you can minify and name the new file as this) and BuddyPress will load it.

All we are doing is folllowing the re-initialization for MatchJAX as specified here
https://docs.mathjax.org/en/latest/web/typeset.html#resetting-automatic-equation-numbering

That should take care of it.

Hi Rob,
Thank you for bringing it. Yes, I see the issue with thi. I will add it in the next version of the plugin.

Thank you.

Hi,
Thank you for the question.

Community Builder is specially tailored for Social community with specific features & customizations. For OceanWP, BuddyPress support is an after thought.

My suggestion will be to give a shot to the themes yourself and select for yourself. Also, if you are using Community Builder Pro, we have a lot more customizations.

In my personal belief, Community Builder Pro is more flexible. I am looking forward to put it on wp.org
