Hi asmecher,
thank you very much for your help.
I follow your instructions, however it does not work, i get the same error message.
I started with OJS since the version 2.2.0 was out, I do only one Upgrade to 2.2.2 and now I do the third to 2.3.6(because i do not get it to upgrade to 2.4.6), but to make a upgrade to a greater version shows to be impossible, because the database splits out. Do you know if someone get it to upgrade from a early version to 2.4.6 or experiences how handle this problem ?
Regards from Germany,
Peter
