I have just upgraded our Moodle site to Moodle2.8.7+ (Build: 20150723)
The site default theme is Shoehorn 2015042303 release 2.8.1.4
Now, when attempting a quiz, the following error message is displayed at the top of the screen, the rest of the screen is white (see image)
“Fatal error: Call to undefined function bootstrap_grid() in /var/www/moodle/theme/shoehorn/layout/secure.php on line 19”
I noticed that the quiz was opening in the popup window, so I tried changing the quiz "Browser Security" setting to "none" and the quiz displayed correctly, without error using the shoehorn theme.
(It was set to “Full
screen popup with some javascript security")
This was not an issue previously in Moodle 2.7.3, but with the latest downloads for Moodle 2.8.7 there is a problem.
As a temporary workaround I have changed the default theme (to FlexiBase) but would like a permanent fix for Shoehorn.
We have Bootstrap 3 theme 2015043000 is installed plus a few other 3rd party themes with no apparent problems.
The quizzes display without errors in the Decaf, BCU & FlexiBase Themes.
Any help would be greatly appreciated.
Thanks in advance,
Craig.
