Sign-up module not working after upgrade

joomlamailer version: 1.7.2
Joomla! version: 1.6.3
PHP version: 5.2.17
MySQL version: 5.0.91

Hello,
I had installed and tested this integration successfully, but then it stopped working - I believe after I attempted to upgrade to joomlamailer 1.7.2. However, I had also been installing several other extensions, so I am not sure if there is a conflict elsewhere.
I am new to Joomla, so I'm not sure where to begin looking for the issue.

Thank you much!

Hello Michelle,

For some reason the signup AJAX call returns a blank response. There is probably a PHP error at some point. Please go the global configuration in your Joomla backend. Set Error reporting to maximum. Let me know when you did that.

Kind regards,
Pete

Hello,
Thank you for your reply.
I set the error reporting to Maximum.

Ok, you can set error reporting back to the previous level. Unfortunately it didn't do the trick. It still doesn't show any errors in the AJAX response. For further debugging I would need ftp access to your site. My email is pete@freakedout.de

Kind regards,

Hello Michelle,

The problem is that you have set the live_site in the configuration.php file. The live site is set without www. If you now visit the site with www then the ajax request will use the live_site url (without www). Browsers have a security feature to block ajax requests to different domains and this way it looks like a request to a different domain to the browser.
You have two options: 1.) Remove the live_site setting from the configuration.php or 2.) Use a canonicalization plugin to have your visitors always redirected to the same url as set in the live_site variable. For example: extensions.joomla.org/extensions/site-ma.../seo-a-metadata/5355 (This also helps avoiding duplicate content penalization from search engines ;)).

Kind regards,
Pete

P.S.: Don't forget to delete the ftp account you supplied me with.

Pete - you are the BEST!!
Took me long enough to circle back and address the site issue, but this is on volunteer time
Thanks bunches, Pete.
Going to rate joomlamailer RIGHT now!
