When users who are using Internet Explorer try to post a reply they get a warning pop-up with the error "Stack overflow at line: 719"
When the OK button is pressed in order to dismiss the message they are navigated to "wp-comments-post.php"
When FireFox is used this problem does not occur.
Does anyone have any suggestion how to fix this issue?
EDIT: When plugin "TinyMCEComments" is disabled this error no longer occurs!
