Hi @asinb27,
First of all yes this plugin works perfectly with both WooCommerce and Easy Digital Downloads. After installing the plugin, when you go to the plugin settings, there is a tab named Third Party
where by default a few WooCommerce pages are excluded from being cached but you can select the option based on what you need from there. Screenshot: https://i.imgur.com/GXJ92BF.png
Now coming to the error log thing you have mentioned, I didn’t understand your question fully. If you are looking for PHP error log, then your ask your host and they can point you from where you can see the PHP error logs.
If you are talking about seeing the logs of this plugin operation then under the General
tab of the plugin settings, enable the Log Mode
(https://i.imgur.com/6nIJPup.png). Once you enable the option and update the settings, then head over to the Others
tab where you will see a section to download the log of the plugin activity (https://i.imgur.com/Le0bhPY.png).
Hope this helps. ??
