Please post a test login. I am not sure we are seeing the same thing I dont see any issues viewing your site but then again I am doing so as a guest. So what is the actual difference on the post? what are you trying to report to us?
In either post I am seeing the member info on the post thats why I am not understanding here what your trying to say your issue is but it appears the issue is with the forum as in some type of forum issue when running the gallery on your site.
Code:
Content visible to verified customers only.
At any rate if thats the case you want to disable all plugins except vbgallery and see if things are fine as this might be a conflict between vbgallery a hack and the forum but lets have you explain exactly what the problem is. Just saying guest and then member with different links that look like the same info to me are not getting the point across as to the issue.
