After upgrading from Schooltool 2.6 to 2.8 I found that the calendar is not working properly.  It may be connected with Bug #1534130 as the results are similar and the error report looks similar but I posted here because it is for a totally different part of the program and doing a very different type of thing. Here are my two problems:

1) If i click on any time period in my predefined schedule for the day (in order to add an event), the screen goes white and I get the following error:

No data received

ERR_EMPTY_RESPONSE
Unable to load the webpage because the server sent no data.

2) If i click on the journal part of any already created (from the course schedule) events on my calendar, things work fine.  But, if I click on the heading of the event (say Matematics 03) I get a white screen with the following error: 

No data received

ERR_EMPTY_RESPONSE
Unable to load the webpage because the server sent no data.

Here is what I find in the error.log file:

****************************************

Like I mentioned before, the response to my click about is the same for both of these events and is similar to what I reported in Bug #1534130.

Any Ideas how I can get these features back and working again?

Thanks!
