Signatures are hidden by default on mobile devices:
Computer they show fine phone you flip it show fine Regular phone doesnt show Using default theme Any ideas?

To test this, members on their mobile can click on their mobile browser settings and turn on "desktop mode". This should display the desktop/PC version of the site, which isn't feasible to use on a mobile, but should display signatures.
Also, if you're using your mobile (or tablet) on landscape mode rather portrait mode, you can see signatures

To test this, change your phone settings to allow "auto rotate", click on a post with a signature (e.g:
https://christisking.cc/threads/how-to-troubleshooting-thread.1210/post-112806) then turn your phone sideways to landscape mode.
If you're on a desktop and still not seeing signatures, navigate to preferences -> tick the box next to "Show people's signatures with their messages" -> scroll down, hit "save".
^ This is unusual; perhaps the member has turned on "desktop mode" in his mobile browser, or he is using landscape mode?
