I have installed the Thunderbird beta (86.0b1) via the snap package on Ubuntu 20.04. I have used it for some months now without any issues. This morning, however, it suddenly opened with a brand new profile and even though my old one is still there I cannot open links from E-Mails anymore. Instead, it prompts me with an empty "Choose application" screen and if I browse to "/usr/bin/firefox" and select firefox, nothing happens. The same pop-up is shown when I try to change the http handler within the settings.
I am trying to setup a local wordpress installation and followed this tutorial to setup LAMP. Unfortunately my Server does not seem to process PHP but I can't find the issue. If I create a file info.php, as described in the tutorial and try to display it in the browser it just shows a blank page.
How can I enable php on the server?
I updated to Ubuntu 18.04 a few weeks ago with little to no problems until now. After an update I installed and a reboot, my sidebar (Ubuntu dock) shows on the secondary screen, which is my Laptop, while my HDMI monitor is saved as the primary and has the top bar with time, battery and so on.
How can I get the sidebar back to my primary screen?
