I guess then we have to do it another way:
1. Download latest imagevue or even better the beta from here
https://www.photo.gallery/?file=imagevuex27beta.zip
2. Upload
everything from the .zip file in a
separate folder. Make sure you don't loose folders on the way.
3. Make sure the new installation works (admin will be at /iv-admin)
4. Move content folder from the old gallery
At this stage you will have your new gallery working. But you will probably want to move configs too.
Move config:
1. Move everything from imagevue/config to iv-config (2.7) or iv-includes/config (2.6)
2.
For 2.7 only: rename iv-config/configUser.xml to config.xml
If you edited themes then you need to move your theme folder to iv-includes/themes.
But if you've edited one the default themes, make sure to rename if (say from default to mydefault)
This is it.
