I have a clean install of the latest Moodle 2.0 Preview 4 (20100802).

I have created a topics course.

When I click "Filters" in the Settings Menu I see "Coding error detected, it must be fixed by a programmer: $PAGE->context accessed before it was known." with a stack trace of:

• line 331 of /lib/pagelib.php: coding_exception thrown
• line 585 of /lib/pagelib.php: call to moodle_page->magic_get_context()
• line 1216 of /lib/weblib.php: call to moodle_page->__get()
• line 3433 of /lib/accesslib.php: call to format_string()
• line 47 of /filter/manage.php: call to print_context_name()

When I attempt to do anything with the file manager, and click "Server Files" I get the same error.

This is also happening at user/managetoken.php with stack trace:

• line 331 of /lib/pagelib.php: coding_exception thrown
• line 585 of /lib/pagelib.php: call to moodle_page->magic_get_context()
• line 1216 of /lib/weblib.php: call to moodle_page->__get()
• line 828 of /lib/pagelib.php: call to format_string()
• line 30 of /user/managetoken.php: call to moodle_page->set_title()
