New Post Image Upload Error

[Mike66]

Steve on the SMF Forum suggested that I move this post here:

I have moved my forum to a new server ( I'm still running 2.0 ) and everything is working fine apart from 'Post Image Upload'.

When we use Post Image Upload, it uploads the image to the gallery - but it doesn't insert the image linking text into the post and it displays an error in the Post Image Upload pop up box that says:
"Forbidden"
"You don't have permission to access this resource."

I have tried everything that you suggested in your SMF Forum replies - and the error is still happening. I have checked with my webhost and the Malware Scanner warning is not an issue and is not blocking anything.

The path that Post Image Upload is struggling to access is:

Can you help with any more suggestions please? I am really struggling to resolve this one!

Best wishes
