Using "link" as a field name

Is link now a reserved word in MySql ?

I have link as a field name in many existing tables. And these tables work perfectly.

But yesteday, I tried to add a field called link in a new table, and I get an error message saying "“Bad Request- Your browser sent a request that this server could not understand.”

TIA
PAtricia

That message isn’t a MySQL message, so I don’t think MySQL has anything to do with it.

OK, thanks.
I got in touch with my hoster, and turns out it was an error on their side.
