Endless Loading Data on pagination

Just installed Piwik 1.9.1 for the first time. After searching this forum problem with No Data aviable was soled, but the second problem a have from begin of using Piwik is that in all browsers, differents PC’s i can’t use pagination in ALL popup windows on dashboard - endless Loading Data appears and that’s all ((( I have attached screenshot.

Who knows what to do ?

I think the issue is being tracked and fixed in UI: use POST request instead of get to avoid parameters logging · Issue #3359 · matomo-org/matomo · GitHub

You can try applying the patches or wait for next release.

try using the latest beta where this should be fixed: http://builds.piwik.org/piwik-1.9.2-b2.zip

Thanks a lot ! after upgrading to latest beta the problem disappeared.
One more question - I don-t know how to install patches (( can you tell me how ?

As the problem disappeared you do not need to apply any patch

I understand this ))) but I want to know how to install patches, maybe in future I will need it ?
