I'm trying to upgrade an old version (1.2.8) of zenphoto to the latest.
I made a duplicate of my website & database on the same server, and tested it was all working before proceeding to upgrade it. Deleted index.php, /themes and /zp-core and uploaded new ones as per the instructions.
On attempting to upgrade, I just get the following error: "You must be logged in to run setup". I WAS logged in to admin (on the duplicate site) before starting the upgrade! Going to admin, I just get the same error.
I've also tried going directly to the setup file, but it also gives me that error!
I've found almost nothing on these forums about this particular error, so I have no idea of what I'm supposed to do now. Its not the first time I've upgraded a zenphoto site, but it is the first time I've come across this issue.
I'm so glad I made a duplicate of the site to test this on first ;)
Can someone advise me on how to proceed with the upgrade please? Thanks!
