ntopng 4.2 needs to be updated to 4.3, Bug when accessing a host for details
On pfsense 2.5, installing ntopng from package manager ntop 0.8.13_9 which is 4.2 version of ntopng, after logging into ntopng, results in a corrupt web page when clicking on a host for details, this has been fixed in 4.3 by ntopng team.
I installed 4.3 manually from ntopng pfsense doc, and confirmed this resolves the issue.

upvote for this.
P.s. Also don't know what happen with pfsense repo, but installing ntopng from scratch with version of package 0.8.13_10 which should install ntopng-4.2.d20210309,1 - actually install ntopng Community v.3.4.0 at 24/11/2021, previously there was no such bug and I hav 4.2.0 version.
