Hi,

I finally upgraded to Piwigo 13.3.0 and changed to a new theme (Bootstrap) which has quite a good responsive layout.

Everything is fine but at the photo detail page I got an error message:

Warning: Undefined array key "HTTPS" in /homepages/1/d16368409/htdocs/uniformen/_data/templates_c/1b3afv1_1iyrv7g^bfe90babc349c0c324bbc7d6292fc64ba67dc287_0.file.http_scheme.tpl.php on line 26

Check here as an example: http://uniformenportal.de/picture.php?/ … tegory/119

I think it is something with the theme, so I disabled most of the extensions (only 4 still activated).

Thank you for your help ... greetings from Berlin
