Dear,

after moving my Piwigo installation to another shared hoster, I am unable to use it anymore.
I did moving by a full movement of the webfolder and the corresponding database.

When I enter the site, I see the following errors on top of it:


Warning: ini_set(): A session is active. You cannot change the session module's ini settings at this time in /var/www/vhosts/deubner.eu/httpdocs/media.deubner.eu/include/functions_session.inc.php on line 46

Notice: A session had already been started - ignoring session_start() in /var/www/vhosts/deubner.eu/httpdocs/media.deubner.eu/include/common.inc.php on line 156

Notice: Undefined index: force_https in /var/www/vhosts/deubner.eu/httpdocs/media.deubner.eu/plugins/Force_HTTPS/main.inc.php on line 154

In addition to that, I am unable to login, as I am told that

"Cookies are blocked or not supported by your browser. You need to accept Cookies to login" and redirected to another login screen.

As I did not prevent cookies, I have no idea what causes this.
Any help would be highly appreciated.

Thank you in advance

Piwigo version: 2.9.2
PHP version: 7.1.14
MySQL version: Shared Hosting, unable to retrieve information
