Thanks for explanation..
When you login to Admin panel, you have a WPide editor (3 items above Ajax search pro) which gives you access to all files you need to edit. Is that enough for you?
For now, I've changed the search to another one, so you can use a temp page to do the experiments.
I will enable the security plugin, then you can login from the url i put in ftp field (private) or give me an email, then I will send you the credentials again.
Please let me know if you need anything else to make it work… it would be good for next update..
