Unknown Modifier

I’ve searched the forums, and I have seen these errors in general, but not specific to the problem I am having. My comments were working fine. I made no adjustments or anything, yet now all of a sudden I am seeing the following after trying to enter a comment:
Warning: Unknown modifier ‘1’ in /home/jaycaru/public_html/wp-includes/functions.php on line 1348
[Multiple errors repeated]
The comment will post, but I am still seeing this. Any ideas?
