Hi guys! I would like to say a BIG THANKS for this plugin wpForo. The idea is perfect, but wpForo is a young product and I hope that you will make it better and better!

In this version I have found some problems and would like explain their.

1. Untranslated phrases:

file: ajax.js
line: 183

$("#wpf-reply-form-title").html('Reply with quote');
Changed it to:
$("#wpf-reply-form-title").html(wpf_ajax_obj.phrases['reply with quote']);

line: 427

$("#wpf-reply-form-title").html('Edit post');
Changed it to:
$("#wpf-reply-form-title").html(wpf_ajax_obj.phrases['edit post']);

I added this phrases in admin part and now they are displaying correct.

2. The problem with subforums was described by pepi1025. I resolved it by changing file index.php (in folder wpf-themes). The problem was also with main forum title and links to topics in main forum which has a subforum. These links contain a slug from subforum kinda they placed in that subforum.

after line: 67 I added line 68:
<?php $forum = $wpforo->forum->get_forum( array( "slug" => $forum_slug ) ); ?>

After this change all works fine.

3. I have transferred some part of topics from my old forum. They was transferred with correct date and time, but when I am showing such topics an order of posts is incorrect. I changed next:

file: class-posts.php
line: 260
'orderby'		=> 'postid', 	// forumid, order, parentid
changed it to:
'orderby'		=> 'created', 	// forumid, order, parentid

Now order is right.

4. I don't know why, but on my production server I have a problem with date and time display changing. I would like to see date and time of posts like in WordPress not 'ago'. But this option in admin not worked for me. In any status of this option I see 'ago'. On local server everything works good. I a little bit changed wpforo_date function. May be this will be useful. I added a var $wfwpdate, see below.

function wpforo_date($date, $type = 'ago', $echo = true ) {
	global $wpforo;
	$d = $date;
	$sep = ' ';
	$timestamp = strtotime($date);
	$timezone_string = get_option('timezone_string');
	
	$current_offset = get_option('gmt_offset');
	
	$wfwpdate = wpforo_feature('wp-date-format', $wpforo);
	
	if(!is_string($type)) $type = 'ago';
	
	if( is_user_logged_in() && !empty($wpforo->current_user) ){
		if( isset($wpforo->current_user['timezone']) && $wpforo->current_user['timezone'] != '' ){
			if(preg_match('|UTC([\-\+]+.?)|is', $wpforo->current_user['timezone'], $timezone_array)){
				$timezone_string = '';
				$current_offset = str_replace('+', '', $timezone_array[1]);
			}
			else{
				if(in_array($wpforo->current_user['timezone'], timezone_identifiers_list())){
					$timezone_string = $wpforo->current_user['timezone'];
					$current_offset = '';
				}
				else{
					$timezone_string = '';
					$current_offset = '';
				}
			}
		}
	}
	
	if( $timezone_string == '' && $current_offset != '' ){
		$timezone_string = timezone_name_from_abbr('', $current_offset * 3600, false);	
	}
	
	if( class_exists('DateTime') && class_exists('DateTimeZone') && $timezone_string ){
		$dt = new DateTime("now", new DateTimeZone($timezone_string)); 
		if( method_exists($dt, 'setTimestamp') ) $dt->setTimestamp($timestamp); //DateTime::setTimestamp() available in PHP 5.3 and higher versions
		if( $type == 'human' && !$wfwpdate ){
			$d = human_time_diff($timestamp);
		}
		elseif( $type == 'ago' && !$wfwpdate ){
			$d = human_time_diff($timestamp) . ' ';
			$d = sprintf( wpforo_phrase('%s ago', false, false), $d );
		}
		else{
			if( $wfwpdate ){
				$date_format = get_option('date_format');
				$time_format = get_option('time_format');
				$type = $date_format . $sep . $time_format;
			}
			$d = date_i18n($type, strtotime($dt->format('d.m.Y H:i:s')));
		}
	}
	else{
		
		if( $type == 'human' && !$wfwpdate ){
			$d = human_time_diff($timestamp);
		}
		elseif( $type == 'ago' && !$wfwpdate ){
			$d = human_time_diff($timestamp) . ' ';
			$d = sprintf( wpforo_phrase('%s ago', false, false), $d );
		}
		else{
			if( $wfwpdate ){
				$date_format = get_option('date_format');
				$time_format = get_option('time_format');
				$type = $date_format . $sep . $time_format;
			}
			$d = date_i18n( $type, $timestamp);
		}
	}
	
	if( $echo ){
		echo $d;
	}
	else{
		return $d;
	}
}

Now it works! I don't know what a problem with this.

5. Extra space after phrase "Edited". It looks not good by eye. The problem was in next:

file: functions-template.php
line: 617
$edit_html = '<div class="wpf-post-edited">' . wpforo_phrase('Edited: ', false) . wpforo_date($post['modified'], 'ago', false) . '</div>';
changed it to:
$edit_html = '<div class="wpf-post-edited">' . wpforo_phrase('Edited:', false) . wpforo_date($post['modified'], 'ago', false) . '</div>';

6. Layout 3 modification. For me is logic when the author link in the column "Last post" goes to this last post not to author page.

And it is very difficult sometimes to click on a small arrow near author link. So I have modified template file: topic.php / layout 3

from:
<div class="wpforo-topic-stat-lastpost">
    <span style="white-space:nowrap">
        <?php wpforo_phrase('by') ?>&nbsp;
	<a href="<?php echo esc_url($last_poster['profile_url']) ?>">
	    <?php wpforo_text($last_poster['display_name'], 9); ?>
	</a>
	<a href="<?php echo esc_url($wpforo->post->get_post_url($last_post['postid'])) ?>" title="<?php wpforo_phrase('View the latest post') ?>">
	    <i class="fa fa-chevron-right fa-sx wpfcl-a"></i>
	</a>
    </span><br>
    <?php wpforo_date($last_post['created']); ?>
</div>

to:
<div class="wpforo-topic-stat-lastpost">
    <span style="white-space:nowrap">
        <a href="<?php echo esc_url($wpforo->post->get_post_url($last_post['postid'])) ?>" title="<?php wpforo_phrase('View the latest post') ?>"> 
        <?php wpforo_phrase('by') . '&nbsp;' . wpforo_text($last_poster['display_name'], 9); ?>
            <i class="fa fa-chevron-right fa-sx wpfcl-a"></i>
        </a>
    </span>
    <br>
    <?php wpforo_date($last_post['created']); ?>
</div>

7. Please, add a function for changing a user of post. Now for this I every time go to phpMyAdmin. 

8. And the main problem is a number of queries! I checked on local server. I made a clean installation of wpForo and added test topic with 3 replies, opened this topic and page generation - 120 queries of wpForo. 

On my production server page generation of topic with 10 replies - 310 queries of wpForo. 

Topic with 1 question and 2 replies - 224 queries. This is incredible! (For monitoring I use plugin "query monitor")

I think that the main goal for next release must be a decreasing a number of queries and optimization. Not a new functions.

Also I have found some strange queries. In topic with 1 question and 2 replies. Look at image below. Queries: 115, 116, 133, 134. 

Topic id = 588, it has 3 messages in my database these messages have parentid = 0.

I don't understand what do these queries.

Thank you! I hope my post will be useful for improve wpForo. I really like it!
