thanks for your suggestion
but i did not make a backup, is there any Other solutions
For the conformation, what i did is :
ojs -> config.inc.php -> installed = Off -> (If you are upgrading an existing installation of OJS 2.x, click here to proceed.) -> http://mydomain.com/ojs/index.php/index/install/upgrade
in the Upgrading from OJS 2.x doc :
Obtaining the latest OJS code
The OJS source code is available in three forms: as patches against older
releases of OJS, from read-only github access, and as a complete
Patching or updating from github is the recommended approach if you have made
local modifications to the system.
Patch files for older releases of OJS can be downloaded from the OJS web site.
To update by patching, download the appropriate patch file for your current
version of OJS and run the following command from your OJS directory:
$ patch -p1 < PATCH_FILE
Upgrading the OJS database:
If you do not have the PHP CLI installed, you can also upgrade by running a
web-based script. To do so:
- Edit config.inc.php and change "installed = On" to "installed = Off"
- Open a web browser to your OJS site; you should be redirected to the
installation and upgrade page
- Select the "Upgrade" link and follow the on-screen instructions
- Re-edit config.inc.php and change "installed = Off" back to
"installed = On"
this what i did, i hope this is not rong
