Thank you for the information, I will read them.
I think my site does need some clean up, because those tags just reappearing automatically, must be the doing of a plugin.
Thank you Rae. I will give it a try. Can you give me an example how to clear it in the database? Even though I don’t much experience with database but if I don’t start doing, I will never know how to do it.
If it is very advanced, I am willing to learn from the basics. I have read couple php books and know it is probably not enough but I really want to get more advanced in dynamic websites.
