i18N Gallery won't Activate

[sarnaiz]

Having issues getting this plug in to activate.

I downloaded new version, unzipped , then uploaded. It did not write files where needed because I could unzip on the server or activate it (not sure which does the writing), so I followed instructions here http://mvlcek.bplaced.net/get-simple/i18ngallery under installation, but still no luck. I added the cookie snippet to the gsconfig and all the other things on the list.

I am using version 3.1. I had installed The photo gallery first but didn't get it working the way I wanted, so I switched to this plug in. I have removed the photo gallery plug in files from the plug in directory. I also found one in the data/pages folder and removed it. Could there be something else causing a conflict?

My test site is here http://sherriarnaiz.com/CMS/GS/

I'm trying to create a sandbox for my clients to test this. Wanted to try out responsive templates and add some new plug ins so I wiped out my old site and upgraded to 3.1. I have been at this all day and had numerous other problems. Removed and reuploaded files several times to fix. Now site is functional but this plug in (which I added last) is not working.

Any suggestions for how to fix this are much appreciated.

Thanks!
