Hi
First kindly create an override for the module from template manager > open the JA Platon template files > overrides > mod ja twiitter Now open /templates/ja_platon/html/mod_jatwitter/default.php
And Change the line: 38
<img src="<?php echo str_replace('http:','https:',$item->profile_image_url); ?>" style="width:<?php echo $iconsize; ?>px;" alt="<?php echo $item->name; ?>" class="ja-twitter-avatar" />
And the line: 77
<img style="width:<?php echo $sizeIconfriend; ?>px;" alt="<?php echo $friend->name; ?>" src="<?php echo str_replace('http:','https:',$friend->profile_image_url); ?>" />
Save and check.
Regards
