- The Issue -
WP Super Cache isn't generating the static cache file if AddThis 2.4.0 or 2.4.1 are active. The timestamp is output normally (so it's easy for this issue to go unnoticed at first), but it actually ends up re-generating the page on every pageview.
- Diagnosis -
WP Super Cache's debug message was that a GET variable was present so supercache was being disabled (WP Cache was still being utilized). Specifically, !empty( $_GET ) within WP Super Cache's wp-cache-phase2.php was causing "Supercache disabled: GET or feed detected or disabled by config." to be shown.
- A Temporary Fix -
I reverted back to AddThis 2.3.2, and WP Super Cache went back to functioning properly. I'm guessing there's quite a few people out there that use both AddThis & WP Super Cache, but I haven't yet found what's causing the issue myself.
Any help would be greatly appreciated as I'd like to use the latest & greatest AddThis in combination with WP Super Cache. Thanks!
