take out the spaces after the l's in url and put it in the signature spot. HTML is off on my profile too, so if copying this and taking out the spaces doesn't work, maybe it does have something to do with how many posts you have - but I don't think so.

Let me know if the above doesn't work because it worked for me - just remember to delete the spaces after the l's.
