When I try to use the import tools in OJS 2.0.2 to import the data in 1.1.8 to 2.0.2, I receive an error:
- DB Error: Duplicate entry 'g' for key 2
Interestingly, I can see 171 users in the database of the ojs2.
I tried to delete the 172th user in the ojs1 database but the same error occur.
My system is working with the following environment:
- OS platform WINNT
PHP version 4.4.1
Apache version Apache/2.0.55 (Win32) PHP/4.4.1
Database driver mysql
Database server version 4.1.10
Is there any way I can do to know what is going wrong?
Is there any advice for my upgrade?
Thanks a lot.
