Hi All, I have upgraded an old server to new server, I have installed the same version of zope (Zope-2.10.9). I am having difficulties importing .zexp files which has MySQL connectivity. I am getting the following error (the password of mysql is retained the same for connecting the database): 2016-05-30T00:00:17 ERROR ZRDB.Connection Error connecting to relational database.
