That's fine. But you imply that you have made your own customisations to the Moodle code. Those instructions are written under the assumption that you haven't done that - or that if you have, you know enough to modify the upgrade instructions.

That depends how you cusomised things, and how you did the update.

If you originially downloaded 1.8.2 as a zip file, then edited the code, but then downloaded 1.9 and copied the new files over the old ones, then you will have lost your changes. I sincerely hope that the upgrade instrucitons tell you to take a full backup before you do anything else.

If you originally got 1.8.2 from CVS, and updated with a CVS update, you won't have lost your changes. See http://docs.moodle.org/en/CVS_for_Administrators.

Why 1.6.x, and not 1.8 or 1.9?

The top level index.php file will correspond to the home page.

Adding

#mod-quiz-attempt .pagingbar a {display: none}
#mod-quiz-attempt .pagingbar a[title=Next] {display: inline}

to your theme should work - in web browsers support CSS properly. It works in Firefox.

That is not really secure. Anyone who reads the code of the quiz modules could work out how to jump to any page of the quiz.

Sorry about the misunderstanding. I sometimes forget that there are people in the world can't tell at a glance that a string of random characters is CSS code, rather than PHP, and so belongs in one file, rather than another.

I have just tried the line of code I gave (in Moodle 1.8.2), and it definitely works. I can think of two possible explanations why it is not working for you.

One possibility is that sometimes web browsers cache stylesheets rather than re-fetching them from the web server each time. So you edit the stylesheet, and nothing appears to happen. Normally, you can fix things by holding down CTRL+SHIFT then clicking on the reload button.

The other possibility is that that for some reason, the gradients.css is not actually being used by your theme. If there are other .css files in your theme, try moving the line of code there instead.
