Admin action interfering with other plugins

Hi,

your plugin has a “route” system in the admin context which intercepts the “act” query parameter to implement distinct actions (for example the copy action).

But you’re checking for this parameter on each admin POST, without verifying if the action is staring from one of your admin pages. Hence is another plugin (in our case “Newsletter”) is posting the parameter “act” with value “copy”, your router intercept it and show the wrong page.

You should fix that behavior checking, for example, the referrer and ensure the post is from one of your admin pages.

Stefano.
