smtp pro configuration show blank screen and can't send mail

[SalarMoghaddam]

When i go to System > Configuration > SMTP Pro it shows me blank page without any information or error. that was working great before!

I downloaded full site and database and import them, in localhost it's working! I have configuration and i can send mails. I have this problem with other smtp extensions, blank screen or can't send email. Is it server problem? something is not installed?

Sorry for my bad english Thank you

Hi SalarMoghaddam,

1. logout from admin

2. clean the cache, removing the contents from var/cache folder

3. login to admin again and check the extension is working
