Https problems with css/js files

[Chingis]

hi!
i use OJS 3.4.0.6, try to install.
i change base_url in config.inc.php to https (its was http), but anyway all css/js files have href = 'http://…".
In browser console:

Mixed Content: The page at ‘’ was loaded over HTTPS, but requested an insecure stylesheet ‘’. This request has been blocked; the content must be served over HTTPS.

Please help me.

Hi @Chingis

You can try to apply this method, edit the file lib/pkp/classes/core/PKPRequest.inc.php to change this line:

$_this->_protocol = (!isset($_SERVER['HTTPS']) || strtolower_codesafe($_SERVER['HTTPS']) != 'on') ? 'http' : 'https';

to this:

$_this->_protocol = (!isset($_SERVER['HTTPS']) || strtolower_codesafe($_SERVER['HTTPS']) != 'on') ? 'https' : 'https';

In some cases this method works.
