Thank you for your post!
-I'd first verify the pop-up blocker is turned off in your browser.
-If you are using SSL, you might temporarily disable to see if issue persists. Unsupported or improperly configured Certificates can cause strange behavior.
-Update Server to 15.0.3, then see if issue persists.
-Check that you are hitting System Requirements for FileMaker Server 15
From there I would recommend contacting support. I hope this helps!
Thanks for the reply.
It was working fine actually . I disconnected network cable from server for 10 min and connected back again. I didn't make any changes in server.
Suddenly , it stopped working. Anyhow , I will try your suggestions and let you know if that works for me.
Did this issue ever get sorted as I'm having the same problem its not the pop up block as the pop up works fine to tell me the file name it just doesn't down load anything
