TOPIC: Frontend CSV export not working

Hi,

I am having troubles getting the frontend CSV export to work. Backend export works just fine, but at the frontend it hangs in the last step. I can select the both the events I want to export and the fields I want to include, but when it comes to the export, nothing happens. I get the message "CSV Export Processing. Please click OK then wait...", and when I click OK, I can wait but no page reload, no download popping up, nothing.

Tested on both Chrome and FireFox, running J1.5.22, DTRegister 2.7.13, Rockettheme template.
Anybody any ideas on how to solve this?
Greetings,

Desd
