I just downloaded the PGREG question Type of Oleg Sychev. I used the last zip file from http://tracker.moodle.org/browse/CONTRIB-2234 ( preg2010-09-15.zip (587 kB)). I unzipped to the moodle/question/type directory. It appears in the menu of questions with the name "Regular expression" but when I click it it shows a blank web page with an error message saying that the web site can't show the page. I'm using version Moodle 1.9.4 (Build: 20090128)
In the notification section it appeared a message that something needed updating. I clicked on the continue button, but I can't use PREG eithe.
Hi Luis,
The PREG question type not being part of regular moodle distribution and being still under development, I suggest you report any problems in the relevant bug tracker thread CONTRIB-2234.
