www.insightfirearmstraining.com I have been using TubePress for years. I am currently using Wordpress 6.1.1 and I have had to deactivate my TubePress 5.1.8. When it's activated it is crashing my site with every page showing a white screen with this message "There has been a critical error on this website." Once I deactivate the plugin meh site returns to normal. Is TubePress not compatible with the newest version of Wordpress? How do I fix this issue?
