I've used GF successfully for about a year. Recently, I developed a site (w/3 GF forms) on my server (all worked great), then moved it via Backup Buddy to the client's in-house server (BTW, I've had success with moving a site with GF to another server in the past; the difference here is that this one is an in-house server managed by an IT group, and I suspect their server setup is causing the issues).
Although the forms appear on the website, and the GF plugin is shown on the list of activated plugins, GF does not appear on the admin menu: no way to edit forms or view submissions or anything else.
Second, in IE7 (that we know of), prior to each form item label and following each form field, the word "none" appears. Does not appear in Firefox or Chrome on either mac or pc.
