The debugging option is the second one down, right under the API key setting on the basic settings.
I think the confusing part is that none of these settings are available when you go to “Settings” -> “EWWW Image Optimizer” (i.e. to page: /wp-admin/options-general.php?page=ewww-image-optimizer%2Fewww-image-optimizer.php).
The only way to access the settings is to go to the “Plugins” page first, then click the “Settings” link under the EWWW Image Optimizer (i.e. this page: /wp-admin/network/settings.php?page=ewww-image-optimizer%2Fewww-image-optimizer.php).
This is very confusing. The settings should be available from the normal settings menu. You should not have to go to the plug-ins page first.
It sounds like it is because you are using multisite and have activated the plugin network-wide. That means the settings are in the Network Admin menu, not the individual site menu.
I see the potential for confusion there though, the single-site options should probably have a note that says something like “for all the rest of the settings, see the Network Admin dashboard.”
Yes, I assumed that as well. Ironically, I could not access the settings from the network admin dashboard. I had to go to the “Plugins” section of the individual site (not the network level), and then click the “Settings” link on the EWWW plugin. When I go to the “Plugins” section of the network admin dashboard, there is no “Settings” link on the EWWW plugin.
Please shoot me an email at https://ewww.io/contact-us/ so we can dig into that further.
