thanks for the awesome plugin. works well, but I am trying to use in a multisite setup.
I am able to access the HTTP Headers settings page
but on the actual page, each of the “edit” links are not properly linked to the subsite, and only is linked to the main site (without /mysite/ ) in it. if i manually put it in there, i am able to change each header setting.
Looks like the change you should have is in views/list.php
line 139 should be changed from
<td><a href="<?php echo $_SERVER['PHP_SELF']; ?>?page=http-headers&header=<?php
