When loading admin/config/search/path/patterns, the forms either do not appear, or only partially appear. (Attached image from original report).
There appears to be several factors here, (not limited to): some of which seem related to (A) Entity Token, some of which seem related to (B) low PHP RAM settings, some of which seem related to (C) static cache and early bootstrap invocation of module_implements().
- Raising memory_limit seems to solve B (and A?)
- Patch #47 seems to solve C (though it is possibly a workaround to flawed core API)
Better diagnosis of the multiple circumstances that cause the problem, which may not be local to pathauto, but rather other contrib/custom/core modules.

I don't know why the pathauto patterns are not showing up... (see attached image)
