Due to zenphotopress does not compatible with zenphoto 1.4.4.1, so I want to downgrade back to 1.4.3.5. Any guideline?

Regards,
Chris
P.S. I already perform database backup before upgrade.

YOu should install the 1.4.3.5 release over your installation. I do not believe you will need to reload the database, but if you run into issues, you should do that.

Thanks sbillard. Confirm overwrite old version success downgrade zenphoto. No DB reload required.

Hope zenphotopress can release new version soon.
