YUI libraries not loading when external
 

OK, a bit more testing and it seems that the local YUI libraries are working when accessed on the intranet (ie. when I am at the school) but not from home.  This suggests that it is a possible firewall issue, but can anyone suggest what to look for with this? Thanks

Group Particularly helpful Moodlers

Think one would have to disclose firewall vendor for anyone to begin to make suggestions there.  More than likely, if you are sure it's not a Moodle caching issue, someone will have to contact the firewall support/provider.

But, It might not be just the school firewall ... that's the end point from your connection to Moodle outside of school.  Example: have a home connection that uses OpenDNS added to their 'firewall' for home customers.  Sometimes (seldom, I might add) OpenDNS has determined (somehow) that a school site is suspect and I cannot hit the school site.

There could also be issues with network ... network has to work before application.  Suggest doing a traceroute from your home location to the school moodle.  That may not complete all the way to the moodle server, but you might discover there is an issue with routing (which you cannot control).  If that is the case, carriers have to get involved.

And there is a situation like this ... had a Moodle Linux server running iptables (server firewall).  Similar issues with teachers/students attempting to access the Moodle from the outside turned out to be in-compatibility with the schools firewall and iptables.  If we turned off iptables on the server, no problems.  We did that until the school replaced their firewall with a better product ... which was also compat with Moodle servers iptables.

Another gotcha to look out for, which you somewhat discovered here.  The YUI2 in pre-2.3.x Moodle worked in various browsers.  YUI3 conflicts with the interpretation of mouse vs touch vs tablet vs 'smart board' inputs.  Newest IE on Windows, Safari, latest Chromium, seem to work, FF and Chrome fail.  AJAX on Moodle stops working correctly.  

Trouble tickets have been posted in several places, including with the YUI development team.

Thanks for the hints and suggestions.

It seems to be only on a couple of particular computer / browser combinations and not consistent. For example, at the moment on my home computer I need to use IE9 rather than Chrome. Not a big issue - but also not helpful if others in future have the same problem.

Thanks again! I really appreciate the community on here!

Did you check the permissions on on /theme/yui_combo.php? See this post: https://moodle.org/mod/forum/discuss.php?d=223060.

I am having similar issues once we throw the system out to the internet.

Did you solve your issue?

Constance
