Hi @wendi_suharmoko,

Did you investigate the names of your PDF files to determine whether the upgrade process was able to move them? Find the name of one of your PDFs and post it here.

Hi @wendi_suharmoko,

Those are both OJS 2.4-style filenames. The upgrade process renames these to a new style of filename during the OJS 3.x upgrade, but it looks like that didn’t happen in your case. The most likely cause is file permissions preventing the upgrade script from doing what it needs to – the upgrade script will generate warnings in this case.

I’d suggest restoring your OJS 2.4.x files directory and database from backup, then running the upgrade process again, watching for warnings.
