i have updated my testsystem to 22.214.171.124 yesterday and now i can`t load Pico CMS sites in iframes anymore.
I´m running nextcloud through the plesk extension on ubuntu 18.04.5.
I integrated some usergroup-specific content through the Pico CMS and External sites. External sites links were set to show only for the specific groups and linked to a Pico CMS site, which was restricted with the “access: group” in the YAML header.
This worked fine with 126.96.36.199 but after updating to 188.8.131.52 i can`t load the Pico CMS sites within the nextcloud iframe anymore.
I get an error message about the server refusing the connection.
I can still load any other HTML or PHP file from my server in the iframe. Also, the Pico CMS pages work fine outside of the nextcloud iframe.
I have tested it on different devices and a new install of nextcloud, but its always the same issue.
Is there a setting for Pico CMS to allow iframe embedding? Or is this a problem with my server configuration?
