Sample app navigation problem

I just downloaded RadZen opened up the sample app. No matter which of the 3 pages I open, I can't navigate forward using the page numbers or the right arrow. Doesn't work/non-clickable. If i hover over the secret right-side dot, I can click that and go to the last page. Then going back and forth is fine - UNTIL I go to page 1 in which case it doesn't work again as described.

BTW: Pages load slowly. Is it this slow in a live environment?

Do you mean that the DataGrid pager doesn't work? Can you check if there are any JavaScript errors in your browser developer tools console or failed HTTP requests?

Since I am mostly using MariaDB I probably won't pursue this package. But I believe the buttons are not firing at all. They seem to be disabled.
