If you’re talking about the hyphen in the Site Title and you’re saying you didn’t add a hyphen in the Site Title under General Settings, then follow these steps to remove it:
1. Go to the Appearance tab and click on Editor.
2. Select “theme-seo.php” in the list on the right
3. Find this line:
$filtered_title = $title.’ – ‘.$site_name;
It’s line 15 for me.
3. Delete the hyphen, so it looks like this:
$filtered_title = $title.’ ‘.$site_name;
4. Update File
The hyphen should be gone.
I hope this helped. ??
