Thank you for your help!
Unfortunately I have the same error even after I have rebooted the server.
In my firefox on a win7 machine everything seems to be o.k.
Did you clear your browser-chache? Or is it maybe win10 related?
EDIT: Tested also gray and crisp theme. No problems on my side with calendar.

Before adding the issues, confirm me this:
- calendar on firefox looks not right only with the gray theme
- about the update: is this a problem that occurs to anyone updating or that happened only to @GG_jr ?
My steps for installing and update WT 5 with Open LDAP:
- First install from here (everything worked fine):
Welcome, WebTop 5! - #3 by robb
with this command:
yum --enablerepo=nethserver-testing install nethserver-directory nethserver-webtop5
- First update from this topic (everything worked fine):
with this command:
yum --enablerepo=nethserver-testing install nethserver-webtop5
- Second update from this topic (Apache Tomcat error):
with this command:
yum --enablerepo=nethserver-testing update nethserver-webtop5 webtop5*
Just added the @webtop_team 
so itâs easier to call Gabriele and Matteo in the topics

In my webtop the date-format in calendar isnât correct.
calendar format is mm/dd/yy but in settings I set dd/mm/yyyy.
seems that changing of date-format in settings have no affect to the calendar date-format. changing startdax of week works.

I canât reproduce it, maybe a problem between different test packages? 
Could you wipe the whole webtop5 installation?
yum remove nethserver-webtop5 webtop5-core webtop5-libs webtop5-zpush
rm -rf /var/lib/tomcats/webtop
yum --enablerepo=nethserver-testing install nethserver-webtop5

How can I install if I have Webtop4 installed already?
I uninstalled using the web interface, then on install it errored as webtop4-core, webtop4-lib, webtop4-zpush still installed. I uninstalled manually using yum, and now I get the following error on /webtop;
HTTP Status 500 - java.lang.NullPointerException
Hi,
sry, was away.
And now first - I like webtop - easy, simple just what I needâŚbut:D
At the moment I have a problem to download Language-pack, donât know why something with DNS? I will give it a try - promised!
OK, I like the cloud, but when I created a link, there is no way to get the link again. So, if I have a file in cloud which I want to send more than one person I have to find the first Email with the link in it.
A post was split to a new topic: [BUG] Cloud: canât share uploaded resources
- Try to uninstall again WebTop 5 as @giacomo said above:
yum remove nethserver-webtop5 webtop5-core webtop5-libs webtop5-zpush
rm -rf /var/lib/tomcats/webtop
- Check again if WebTop 4 is uninstalled:
yum remove nethserver-webtop4 webtop4-core webtop4-libs webtop4-zpush
( rm -rf /var/lib/tomcats/webtop )
- Reinstall WebTop 5:
yum --enablerepo=nethserver-testing install nethserver-webtop5
- Verify if WebTop 5 it works.
I had already tried that, but I did try again, and same problem.
If it has anything to do with it, I have the following packages installed;
Backup, Email, File Server, MariaDB (MySQL) server, Nextcloud, POP3 connector, and have an LE cert.
I am running on a VM, so I was able to roll it back to a fresh updated install, and it was able to install WebTop5 without issue, but current system cannot. But, then all my email is gone.
I get the following error
HTTP Status 500 - java.lang.NullPointerException
type Exception report
message java.lang.NullPointerException
description The server encountered an internal error that prevented it from fulfilling this request.

I think is a major incompatibility between WT 4 and WT 5 (maybe also with Tomcat).
Anyway, the emails should be there even if WebTop canât start in browser. The emails are not kept by WebTop. After I have reinstalled WebTop 5 (please see my issue from above), all my emails was there.
Of course the emails are not in the new installation, after rollback.

But, if WT4 is completely uninstalled, should it not work.
And, that is what I meant, I canât roll back as emails wonât be there, just testing to see if WT5 would install.
Iâm stuck, really want to try WT5 on live system.
Yes, WebTop 4. But beside it, there is also Tomcat and other dependencies. Maybe some of them, as version, are not compatible with the version which came with WebTop 5.
I think basically WebTop 5 can be used on a live system.
Is not finished but can send and receive emails (at least) without issues.
If you need the emails, you can use Thunderbird or other Desktop Email client to download them by IMAP and after rollback and install WebTop 5, you can have them back.
Only if just an issue with the WebTop.
As is written here:
https://nethserver.github.io/webtop5/#roadmap
all basic functions works.
