No. I had to fix it manually.
Found the problem using a backup of a previous version. There are single quotes in the line where there should be double quotes. Here is the corrected code:
$htmlcode ='<center><iframe style="overflow: hidden; border: 0; width: 480px; height: 326px" src="http://stagevu.com/embed?width=480&height=270&background=000&uid='.$matches[2][$m].'" scrolling="no"></iframe></center><br />';
I’ve run into the exact same problem after installing the plugin today, and the only line I have in my .htaccess file is:
AddType x-mapp-php5 .php
Maybe the plugin is written for php4 only…?
