Today I’ve tried to make Webfig skin, just for testing, only few menus removed.
When I’m logging to Webfig as user with this skin selected, web browser window is empty.
Web browser reports: ‘Uncaught TypeError: Cannot read property ‘firstChild’ of null’ in ‘engine.js’.
I’ve tried almost every browser (FF, Chrome, Opera, IE), still the same.
RouterOS 5.14, RB433AH.
Any ideas???
TIA,
Please post your settings from /user, that are used for skin user.
Below are user setting, affected user is userro:
/user group
set read name=read policy=local,telnet,ssh,reboot,read,test,winbox,password,web,sniff,sensitive,api,!ftp,!write,!policy skin=default
set write name=write policy=local,telnet,ssh,reboot,read,write,test,winbox,password,web,sniff,sensitive,api,!ftp,!policy skin=default
set full name=full policy=local,telnet,ssh,ftp,reboot,read,write,policy,test,winbox,password,web,sniff,sensitive,api skin=default
add name=safe policy=ssh,ftp,!local,!telnet,!reboot,!read,!write,!policy,!test,!winbox,!password,!web,!sniff,!sensitive,!api skin=default
add name=skinny policy=local,telnet,ssh,ftp,reboot,read,write,policy,test,winbox,password,web,sniff,sensitive,api skin=testowa
/user
add address=0.0.0.0/0 disabled=no group=full name=grzegorz
add address=0.0.0.0/0 disabled=no group=skinny name=userro
and content of ‘testowa.json’:

}
This skin was also tested on RB751U, ROS 5.14, same problem 
Regards,
Well but did you try to delete the JSON file?
Normis,
Well but did you try to delete the JSON file?
Many times 
Default skin works fine and there is no problem with users with ‘skin=default’.
Problem is with newly designed skin as described above.
Removing this skin (testowa.json in this case) and making new one (even with different name) don’t resolve my problem.
Recently I found other error reported by Firefox: ‘A is null’.
Regards,
email support, we will give you a pre-release version where this should be fixed.
Still the same with 5.15rc1
Packages are dated Mar/29/2012, 7 a.m
Is this latest RC version with mentioned fix?
Regards,
yes of course, we couldn’t give you packages of the future, so we gave you fresh packages that were built an hour before you asked 
we will see why the fix didn’t work on your system.

I’ve asked you because is possible that new version was compiled, but not uploaded to server.
If you need additional information let me know.
Regards,
I confirm exactly the same error, routeros 5.14 at RB750. Checked at all browsers.
Firefox reports: ‘A is null’ at engine.js (line 1).

Do not uncheck the menues “undo”, “redo” and “hide menu” and check again.

It’s workaround only, which shows that Webfig contains some bugs
Webfig is great feature and I hope MT will fix it soon.
Regards,
results into q is null → doesnt work! 
menus “undo”, “redo”, “hide menu” and “safe mode” checked → works, but then after log in “design skin” is active and that user can see everything in design mode, although his privileges are constrained by his group permissions
menu “safe mode” checked, the other three unchecked → z is null → doesnt work
Any other combination of these doesnt work!
Any clues?

It’s a bug… use Ros V5.15
Regards
I tried latest 5.15rc1, it seems that some bugs are fixed, but I’m still unable to create ‘Status’ page.
Regards,
There is a new ROS version (5.15) but my problem with ‘Status’ still exist
If someone have skin with working ‘Status’ page, post it (.json file) please.
TIA,
