Moodle ignores the course theme and uses the site theme to display several course administration pages.
Current course theme is replaced by site theme in various modules
A list shown for which course admin page Moodle wrongly uses the site theme:
Settings - site_theme
Assign roles - course_theme
Grades - course_theme
Groups - course_theme
Backup - site_theme
Restore - course_theme
Import - site_theme
Reset - site_theme
Reports - site_theme
Questions - course_theme
Files - course_theme
In Moodle 1.6 all course admin pages were displayed correctly with the course theme.
I've fixed these in Moodle 1.9 ... can someone else backport them to 1.8 (and 1.7 probably, the issue is related to the roles changes)
Merged all fixes to 1.8 stable myself
The problem of reverting to site theme still occurs
Problem persists also in 1.8.2+ in Admin -> Restore and Admin -> Backup
all reported places should be fixed in cvs (the Backup worked fine for me in 1.8x)
thanks for the report
Problem still not fixed... See MDL-11039
Problem stil not fixed for individual student's Activity Report.
Petr, can you please fix this as soon as possible.
Also maybe linked problem in individual student's Activity Report is non-sticky forced language for actual course, reported in MDL-11584
Fixed activity reports and blogs as well.
