Yes my admin pannel page also breaks when I update to 1.27.0 I tried many things like delete the Plugin Folder via FTP and re install. Also resore from backup. however as soon as i update to 1.27.0 it breaks.
I just had to remove the plugin all togehter and find an alternative. its a shame wasted 4 hours finding it was this plugin that had the issue then trying to fix it
