Iāve noticed Firefox will display a Corrupted Content page for links to this forum followed in Firefox. Opening them in a new tab avoids this issue. Iāve noticed this in every release of Firefox Quantum. Iāve encountered no issues with Vivaldi, Chrome or Safari.
fyi, this issue appears isolated to the help.nextcloud.com forum and no other Discourse forums Iāve checked. Here is the exact error as copy paste.
