Turned out that the since new plug-in requires more memory from the server, few modifications to the php.ini and htaccess solved the problem.
Following lines were added to
php.ini:
memory_limit = 64M
post_max_size = 20M
upload_max_filesize = 20M
htaccess:
<IfModule mod_suphp.c>
SuPHP_ConfigPath /home/USERNAME/public_html/
</IfModule>
