1.6.6
- Fix problems with saving settings. Returns false ONLY when there's an issue with the config file, not when the setting isn't changed. Change other code to cope with that, including updating WPCACHEHOME (#670)
- When saving settings rename the temporary config file correctly, and delete wp-admin/.php if it exists. (#673)
- Fix adding WPCACHEHOME to wp-config.php when advanced-cache.php is not found and wp-config.php is RO. (#674)
