I've been using Zenphoto for a year, all was well.
I decided to do the upgrade (I don't know what version I had before - Nov 2013 is earliest date on local files).
When I logged on this time it gave me the message that my password was too short so i changed it.
I see a similar issue here but I'm not a programmer so I don't want to muddy the water:
https://github.com/zenphoto/zenphoto/issues/908
Then I backed up the data using the admin page zenphoto.
I followed the upgrade instructions exactly - deleted the files online, then uploaded the new ones.
I got the error page saying some files needed to be deleted - they seem to have already been updated on my computer but I had to ok this.
Now I have a blank page.
According to the forum this could be permissions so I checked the SQL permissions on my service provider and ran the "Check database" tool - ok
I had backed up my files, but the site/zenphoto/backup files are .zdp files not .sql
I'm not sure where to upload the replacement
I even re-installed into a fresh folder and get another error page asking for database so i created a new one online but can't seem to point to it.
Mac OS X 6.8 Chrome or Firefox
What can I remove to start over without losing all my photo data?
PS I'm not a programmer, and the first time I installed it worked fine. I use godaddy as a host.
