Are you trying to "export data" but don't get a file? This means that the pop-ups are blocked somewhere. You can easily solve this.
If you work in Google Chrome, you have to check in the url bar at the top right if the pop-up blocker appears. This appears a moment after clicking on "export data".
If you click on the red cross at the top, you will be notified to allow pop-ups.
If you work in Safari you solve this as follows:
- navigate to the Safari menu at the top left
- click on preferences
- open the security tab
- remove the checkmark for "block pop-up windows"
Due to the new update in Safari you may have to try it differently:
- navigate to the Safari menu at the top left when the Onlinewerkrooster website is open.
- click on "preferences"
- open the "websites" tab
- select "allow" behind the Onlinewerkrooster website
