"... missing or wrong .htaccess file ..."
There is a .htaccess file in the startdirectory of the gallery, with the correct web path for the RewriteBase.
Where must the file be located ?
I think in the zenphoto directory, in my case "pic-gal", or in zp-core ?
The first time, after updating, the admin-panel will starts correctly, but when I went out and start it again --> Error 500 ...
I dont understand it, the version 1.2.9 works fine.
Never change a running system *g*
