Thread:Project:Support desk/Missing pages after upgrade from 1.10alpha to 1.16

I can't find related topics on this. I follow the upgrading page to upgrade from 1.10alpha to 1.16 by 1. copying 1.16 into 1.10alpha's directory. 2. run php update.php There's no error messages at all. Everything is smooth.

I can browse the wiki. But lots of data is missing, e.g. users, pages, images... The log shows only 1 activity from Sep. 08 to Jan. 11. We use this wiki to store research data. People access it quite frequently.

My system: Mysql 5.0.77 PHP 5.3.3

Any idea what's going on?

thanks in advnace
