I've installed Moodle 1.5.2 - latest stable version available. Everything went fine. I started to create courses and study what new we have here. Suddenly i noticed that moodle lost style sheet(s) and it looked horrible! I checked source code and everything was ok - lines for styles were in place. I changed various styles (themes) and same problem...And now i've tried with several different browsers from different computers and problems continues.
What should i do now? Cuold this be server problem or is it in Moodle? Is there any moodle settings that reflects like this?
