Hi Justin,
Thank you for replying. I’ve cleared and purged all caches. Since activating and deactivating the plugin seems to make a difference, I was wondering how the hidden feature was implemented.
As I’ve claimed before, when the plugin’s activated the site works fine, but now when I take it off, even though the plugin is removed succesfully the site doesn’t work. What I’m saying is that the plugin does work, but I thought there were some htaccess modifications that would explain this behavior. It’s quite odd.
And since you said the plugin doesn’t modify WordPress files or the htaccess, looks like I’m stuck trying to understand this bug.
