Hi everyone:
I would like to share the following with you all using (or wanting to use this plugin).
A couple of weeks ago, my site (still beta) href="http://www.dombey.com/blog/ went down unexpectedly with a 500 internal server error. You can read the following threads I posted around to get some help and get this solved:

Despite the laborious plugin elimination and reactivation process, the work through phpMyAdmin, .htaccess, etc, etc... I was under the wrong impression that the FeedWorldPress RSS aggregator plugin I use was the culprit one, since many users also reported that it could generate the same error. However, I was wrong. The real culprit was plugin "wp-polls", which from now on I would not recommend to anyone using it. The strange thing about this error in relation to the "wp-polls" plugin, is that the 500 error only came 1 week after installing the plugin - not immediately - a little bit like a time-delayed bomb. So, point being that even if one is using it without a problem at the moment, it looks like one never knows when failure will/could occur.
Who fixed it for me? My host provider after I raised a support ticket with them. Below is an extract of the email I received this morning:
We reviewed your service request which indicates that you were getting an error when viewing your website. We reviewed the error message after reinstalling PHP in your hosting package and it appears that the error is due to your Widget script. After testing your website http://www.dombey.com/blog/wp-content/plugins/wp-polls/php_info.php, we have verified that your web server working properly and database connections are currently serving without issues at this time. Please make sure to check and update your PHP scripts.
Note the "... reinstalling PHP in your hosting package...", which gives you an extend of the damage "wp-polls" created. The plugin was failing on an unknown database class, which through the whole thing out. It even prevented me for a while from accessing my WP admin partition.
Now here you go... the joy of the plugins. This might never happen to you, but it did to me; thus the share.
Many thanks,
Cheers,
Olivier
