[Plugin: AmberPanther WP Include File] Headers already sent warning

Warning: Cannot modify header information – headers already sent by (output started at <install-path>/wp-content/plugins/wp-include-file/ap-ps/dashboard/index.php:3) in <install-path>/wp-content/plugins/wp-super-cache/wp-cache-phase2.php on line 77

It looks like your plug-in is not playing nice with WP Super Cache.

I’m running this plug-in on a multisite and getting the same warning whether network-activated or activated per site.

I fixed the problem on my site by adding the following code to /wp-include-file/ap-ps/dashboard/index.php:
Just before the “<script>” tag:

<?php
if (headers_sent()) {
?>

And after the “</script”> tag:

<?php
}
?>
