I was using your plugin without any problem. Yesterday, I change the server; because of PHP version.
Previously PHP version was 5.2.17. PHP version is 5.3.17 now. The company and server configuration are same without PHP version.
After my website migration, I started to get the error of "Request Timeout" while I was sending bulletin.
The popup is open for app. 30 sec., but it is totaly white page. No e-mails are appear. However the e-mails are sending at the same time. After 30 sec., "Request Timeout" error is appear.
I am sending e-mail by using a SMTP protocol.
Could you help me to solve this problem?
