Sorry about that. Version 2.2.5 should resolve this. It’s in the pipeline now. Here’s the patch if you want to review the changes yourself this time:
https://plugins.trac.www.ads-software.com/changeset?sfp_email=&sfph_mail=&reponame=&new=2144119%40cache-control%2Ftrunk&old=2144069%40cache-control%2Ftrunk&sfp_email=&sfph_mail=

I just had a quick look at your lat update. It should solve the issue.

In cache-control.php perhaps to only enable this to admins you’ll want to put there is_admin && current_user_can(‘manage_options’)

I’m happy to test it soon as update arrives.

Thanks for your work.

> current_user_can(‘manage_options’)

That check is done in admin.php in case someone finds a away to load it directly.
