Hello everyone
How to upgrade from 3.3.0.13 to last version without lost data?
I can’t upgrade from 3.3.0.13 to 3.4.0.5
In test server I can upgrade from 3.3.0.13 to 3.3.0.17 successfully.
Keeped folders(files, public) and file(config.inc.php)
What application are you using?
For example, OJS 3.3.0.13
