I´ve just published my site viennapiano.club and it seems to have a problem with repeaters. Everything is correctly connected and usually it works, but sometimes it happens, that the repeater would show the preset instead of the data. I enabled caching, which makes it better, but still, if you delete all cookies you have the same problem again and gives a bad first impression. If you reload the site a second time it works though.
Im my opinion the problem is that the data is not loaded on time, so I´ve tried to fix it with this code (I´m quite new to coding I have to say):
that shouldn´t be the problem, it´s visible for everyone. And most of the time it works, only when the internet connection is a bit slow or on mobile devices that happens sometimes. But it looks quite unprofessional when it happens and I wonder if there´s a way to change it
