Created Content Type with Free Tagging Cannot Be Submitted IF More Than 3 Tags is Given

Hello guys,

I don't know if I'm at the right place. Anyway, I would like to seek help in this problem I encountered in the content type I created in regards to free tagging. I have created a new content type named 'item' and integrated tags -- Free Tagging -- on it via taxonomy module. Now my problem is, everytime I attempt to create a new item via node/add/item, and put it more than 3 comma-separated tags, i am NOT ABLE to submit the new node/item.

I have observed different behavior of submission denial from different browsers. In Firefox , it just simply turn the submit button unclickable or can be clicked but nothing happens, thus no submission occur. In opera and IE, when you click the submit button, it just load another blank add new item page and the node is not saved.

I am also confused to where the tags is declared in a module -- is it taxonomy or others.

Please help in this issue. Your little idea is of great help to me.

Thanks
