Moodle 2.6.3
I have tried General and Quiz help and noone has answered.
This problem has various parts, which I think might be related. When I create a quiz , if I double click 'Save and return to course', Moodle creates two quizes and the same happens when I create a question, if I double click 'Save changes', Moodle also creates two questions. Copies of questions have been created that are impossible because some of the obligatory field information is missing.
I am unable to import. Moddle reaches 98% and just stops and backup produces the error below.
I also receive the following error message when I try to open a few existing questions:
Coding error detected, it must be fixed by a programmer. See link below.

Can this problem be fixed?
