[Plugin: NextGEN Gallery] Gallery only shows first image

First off I am using the MSSQL version with multisites. I had two problems on install. I had to change the name of the alttext field to altxt. This isn’t an issue.

Two issues remain:

1. 607 bytes of unexpected output. I don’t know what the problem is.
2. Only the first image for the gallery shows on front end and in manage galleries. Images are in db and in file directory.

I am currently trying to use 1.8.1 although the same issues exist using the latest.

Plugin passes health check.

Can anyone help?
