I've tried to investigate the problem on my end.
1 - on desktop with Win 7 and last release of Google Chrome,
2 - on mobile phone with Android 4.4.2 and last release of Google Chrome,
3 - on tablet with Android 5.1.1 and Samsung Internet Browser.
On the same tablet and last release of Chrome it doesn't work.
There is no chance to clear cache data from WikiTree+ because there is no data from sdms.si in browser cache.
I've tried to delete data from wikitree.com, log out/log in, tried direct links when I've been logged out (and all tabs been closed) - nothing changes.
Seems like invalid session or some errors in server cache.
It is important that this behaviour appeared after attempt to select status in one record of suggestions table.
