Error 503

[yashodhank]

I thought it will save time if I do modify XML and import it back to system to save some time.

I have exported QTI Package 2.2 & QTI Package 2.1 of item class with all sub items under it (total: 100)

Then I modified XML using sublime as follows adding MAXSCORE, maxChoices="1", minChoices="1" values from exported (prior edited item using TAO Authoring option inside software)

Now matter what I do, be it exported package of v2.2 or v2.1, I only get 503 Error without any further details, when I am trying to import back package into software.

I have more than 400 questions (in sets of 100 in each item class) to modify and manual work is really too much..

Please help, let me know if I am missing anything..
