This is a scam to make us buy certificates. But even if we did, there
would still be recently added compatibility problems and security alerts
ant it is being backported to 2.12 so that you won't have to wait for
too long. LON-CAPA authors should also try to find alternatives to Java
applets they are using in the content.
> Hello all together again,
> ich have another question on LON-CAPA 2.11.0 regarding the formula
> editor the user gets when clicking on the small pencil-icon right to the
> answer-box where a formula is required as correct answer:
> I got a request, the editor does not start correctly. I verified that by
> klicking the icon described above and got a "blocked by security
> settings"-Error in Java (using actual Firefox on patched Windows, actual
> Java RE). The error ist described on
> https://www.java.com/en/download/help/java_blocked.xml and the third
> characteristic occurs ("Missing required Permissions manifest attribute
> in main jar"). The described workarounds (see my link) are functional
> but not the favored solution as not all users realize what they are doing.
> As the cause of the error for me seems to be the missing "permissions"
> attribute in MainApplet.java which I associate is part of and maintained
> by LON-CAPA (is it?), I hereby communicate the problem hoping for a
> solution in a coming relase - is this possible? If you need more
> information on that issue, just send me an email :)!
