Error during save permalink

[sebastian.pisula]

During save permalink I have question: Are you sure you want to do this? And I can't doing nothing.

@sebastian.pisula:

I'm having a hard time trying to replicate this bug. The only reason that this should show is that if you are trying to enter in a false structure for either the permalink or the category structure. The message is trying to advise you against saving, thus not allowing you to. This isn't a "bug" to my knowledge in WordPress, more of just a support thing. Double check your input and if you still get the error if you could post your input when you change the permalinks I would appreciate it if you would also post that here.

Here is the code in options-permalink.php that references (granted down the line) the error message "Are you sure you want to do this?"

if ( isset($_POST['permalink_structure']) || isset($_POST['category_base']) ) {
	check_admin_referer('update-permalink');

Feel free to open with steps to reproduce if this still happens, but I cannot seem to replicate this.
