i am using ojs 22.214.171.124. a few weeks ago, ojs was no problem. but a few days ago, in the Administration> Site Setup> Languages setting, Locale was marked with an asterisk (*), whereas previously it appeared English and Indonesian.
Then when I tried to click Install locale, an error message appeared:
Downloading language packs from the Public Knowledge Project web server is not currently available because:
Your server does not have or allow execution of the GNU “tar” utility.
OJS is unable to modify the locale registry file, typically “registry / locales.xml”.
Language packs can be manually downloaded from the PKP web site.
I have installed tar on my ubuntu and previously there was no error like this. Is this because of the permissions of the file or directory? or is there a missing configuration?
My apache error.log :
