wp-super-cache/pluginsdirectory results in the endless redirection loop which block the blog front-end and admin back-end access. From version 1.5 SIG plugin checks if WP Super Cache is active and create then empty index.php file for the
wp-super-cache/pluginsdirectory without redirection directive. The incompatibility issue is resolved this way.
If you have WP Super Cache under different path, not the default
wp-super-cache/and met with redirection loop problem then remove redirection directive from
wp-super-cache/plugins/index.phpfile manually. Delete first line with SIG stamp too. WP Super Cache loads and executes all
.phpfiles which it founds at the
wp-super-cache/folder. So this file MUST be empty, e.g. standart WordPress dummy index.php:
<?php // Silence is golden ?>
This will resolve your problem. If it doesn’t – write a comment here. I will try to research your issue and help you.
You can check the
wp-super-cache/plugins folder for exclusion from the SIG plugin scan process at the SIG settings page also.
Thanks to Donncha (WP Super Cache plugin author) for the quick answer about his plugin functionality.
