CMS Made Simple Forums

Hi! I installed the latest release of calendar module. I've created 1 event to check if it shows on the page (done as calendar option not list). I've put proper instruction: {cms_module module='Calendar' table_id='big'}. Everything looks ok in IE and Opera Browsers but in Firefox the event doesn't show at all. I've checked the source of a website and I noticed that theres no such thing like proper code generated - IE and Opera does have the code. Im wondering why? I didn't changed anything. What am I doing wrong? Please Help!

So I decided to chceck all my css and templates and I found something strange. When I put calendar module into other page with the same template as my main page(where firefox went wrong) - It worked! But I still don't know what was the problem. The point is that main page and the other page where exactly the same. The only diference was the position in the menu, so I changed other page into main page and it works. The problem seems like it never existed. So if anyone have the same problem, just do as I did It works, Don't know how but it works.
