Hi
Yes already doing that and try the theme on the fresh new install of OJS 3.2.1.
The problem however still persist for any of custom theme.
I try to activate display error on config.inc.php.
Here the healthScience theme on index page :
This is what I got and I think this error not specifically about my problem as I explained above
And in the apache error log, I can say that there are not any single line that related to the this template load error.
