Hi,
I’m not really sure what happened that day when I said that the problem was solved. The next day it wasn’t working any more. I waited some days to be sure it is not a cache-problem. Maybe I didn’t look close enough and there was still an error…
A month later I decided to look after the problem again. I found a solution for the problem by inserting
if ( is_ssl() ){
$generate_settings['logo'] = str_replace( 'http://', 'https://', $generate_settings['logo'] );
}right behind the comment //Site logo in line 555 of the file template-tags.php
Because I’m not good in php I don’t know if this is a good solution – but it works.
But I realized that there are other pictures deliveres by http instead of https: the wp-post-image has a tag src where the image is delivered by https – it also has a tag scrset wher the image is delivered by http.
I searched a while where the code for wp-post-image is generated, but I found nothing. So I have no idea to fix the problem…
