I just upgraded from 3.1.6 to 4.1.11 and Tubepress now doesn't work at all. My pages simply return the following error:
Fatal error: Class 'tubepress_impl_patterns_toposort_TopologicalSort' not found in/nfs/c10/h04/mnt/150983/domains/videomi.com/html/tubepress/src/main/php/classes/tubepress/impl/html/CssAndJsRegistry.php on line 315
There was also a file called "tubepress-content/config/boot.json" in the old installation. I'm using the standalone version.
Any suggestions on how to fix this?
