That's actually smarter, I totally didn't think of it! Thanks!

Instead use his suggestion to load FA icons, add this to your Wordpress, header.php (sorry I forgot or didn't mention his before):
[code]
<link rel="stylesheet" href="http://localhost/root_integrations/phpbb32/assets/css/font-awesome.min.css?assets_version=9">
[/code]

Same replacement as first post in phpbb_last_topis.php
[code] $w3all_post_state_ru = (isset($phpbb_unread_topics) && array_key_exists($value->topic_id, $phpbb_unread_topics)) ? $w3all_post_state_ru = '<span style="color:#BC2A4D"><i class="fa fa-file-o" aria-hidden="true"></i></span>' : '';[/code]

hi! i'm over right now to check before to start 1.7.2 and looking for requested additions.
do not know if this will be added but looking on fly into this feature (and due to latest little fix to the js code that render columned colors (still not perfect for topics lists) on phpBB template) i see that the folder
[b][i]phpbb32/assets/css/[/i][/b]
contain the [i]font-awesome.min.css[/i]
so you can avoid to load the file from external resource and load the one embedded already into phpBB adding on wp header the css style:
[code]
<link rel="stylesheet" href="http://localhost/root_integrations/phpbb32/assets/css/font-awesome.min.css?assets_version=9">
[/code]
so replace the code on widget, as suggested by @kaspir.
(just to mention on fly)

Nice! We can add this by default for sure.
Let prepare 1.6.7 to be WP widget code fixed on last topics and remove some messy thing, and we add this by default!
This a [i]sticky[/i] post!

[b]Step 1:[/b] Edit your WP theme's (preferebably child's) header.php and add this right before the </head> tag. Be sure to use YOUR path to phpbb.
[code]<link rel="stylesheet" href="http://localhost/root_integrations/phpbb32/assets/css/font-awesome.min.css?assets_version=9">[/code]
[b]Step 2:[/b] Open phpbb_last_topics.php and find:
[code]$w3all_post_state_ru = (isset($phpbb_unread_topics) && is_array($phpbb_unread_topics) && array_key_exists($value->topic_id, $phpbb_unread_topics)) ? $w3all_post_state_ru = '<span style="color:red">&#9754;</span>' : '';[/code]
Replace with:
[code]$w3all_post_state_ru = (isset($phpbb_unread_topics) && is_array($phpbb_unread_topics) && array_key_exists($value->topic_id, $phpbb_unread_topics)) ? $w3all_post_state_ru = '<span style="color:#BC2A4D"><i class="fa fa-file-o" aria-hidden="true"></i>&nbsp;</span>' : '';[/code]
[b]Step 3:[/b] Upload both header.php & phpbb_last_topics.php to the proper directories, and refresh your page!

Instead of the original red finger point, the "unread" topic icon will now match the original color & FA icon from phpBB3.2 prosilver theme.

Hope someone enjoys this edit I've done for myself. Just sharing!

Another minor change I made, was I moved the ".$w3all_post_state_ru." var in phpbb_last_topics.php to the beginning of the <a> element, so that my FA icon now appears BEFORE the topic title, instead of after. This will need to be done on a few different lines, but should look something like this:
[code]echo "<li>".$w3all_post_state_ru." <a href=\"".get_home_url()."/index.php/$wp_w3all_forum_folder_wp/?forum_id=$value->forum_id&amp;topic_id=$value->topic_id&amp;post_id=$value->post_id#p$value->post_id\" title=\"Last Post: $value->post_subject\">$value->topic_title</a><br />".__( 'by' , 'wp-w3all-phpbb-integration' )." $value->topic_last_poster_name ".__( 'at ' , 'wp-w3all-phpbb-integration' ) . date_i18n( 'H:i M d, Y', $value->topic_last_post_time + ( 3600 * get_option( 'gmt_offset' )) ) ."</li>";[/code]
Only move the var on echo lines. Enjoy.
