OJS3: No Access-Control-Allow-Origin header is present on the requested resource (Chrome)

We have those issues with several installations that in some browsers icons are visible and in some not. I think that is needed to double check is it apache configuration. If apache does not allow something how some browsers can get icons while other browsers can’t. ?
I think that this issue deserves more detailed examination.

Thanks

Apache is configured by a series of conf files which live outside of the web root. For example, in RHEL these usually start with /etc/httpd/conf/httpd.conf, which then references /etc/httpd/conf.d/*.conf, etc. Apache can be further configured with .htaccess files which live inside of the web root.

Either the main configuration files or the .htaccess overrides can be used to make a mod_rewrite rule such as this (provided .htaccess overrides are allowed by the main configuration files).
