Our IT staffs recently updated our virtual sever to version 2.15 (from 2.13). As I'm uploading problems I discovered several issues:
(a) repeated complains about "Provided value [a particular topic] is not in my chapter taxonomy"
(b) math symbols not display correctly
(c) cannot generate pdf files
For (a): Several problems have the tag "probability" (subject) -> "discrete probability" (chapter). When I go to the library browser and type "probability" for subject, indeed there is no chapter called "discrete probability". We encounter no such error message until 2.13. I do notice that under 2.15 there is an option for editing tags (cf first page of enclosed screenshot) that's not available in 2.13.
Is that the source of the problem, and how would I resolve this? (I hope we don't have to manually edit them all!) Do students see this error/warning message?
For (b,c): The new server does not seem to be able to handle latex symbols, even for a simple problem like this (cf page 2 of enclosed screenshot for the error message):
--------------------
BEGIN_TEXT
$PAR
Suppose that \(A)\ and \(B)\ are two events for which
\(P(A) = $a\), \(P(B) = $b\), and \(P(A\;\mathrm{and}\;B) = $banda\) Find
\(P(A|B)\).
$PAR
\(P(A|B) = \) \{ans_rule(15)\}
$BR
END_TEXT
-----------------------------------
I also have not been able to generate any pdf; I assume it's caused by the same underlying issue (?). What should I go about resolving this?
The server update/maintainence was done by our IT staffs. I believe they use the live image, but that's the extent of my understanding of their work. How should I work with our ITs to address these problems?
MANY THANKS for your last-minute help and guidance!
