Calendar CSS not rendering with default WP theme and no other plugins

Hello – I hope you can help.

My calendars’ css will not render and/or load.

SEE: http://dev.silvervalleycommunitychurch.com/calendar/

I upgraded my all-in-one plugin to the latest version 2.3.4, WP, my themes, all my plugins are up to date. For some reason the CSS to the calendar is not loading or rendering. Granted it was displaying fine.

(see extra details at end)

I have disabled all other plugins, and loaded a default WP theme to test for compatibility. Still will not render CSS!!!

I have tried changing the permissions on “/wp-content/plugins/all-in-one-event-calendar/cache” folder (and “twig” folder) to 777 – that did not work. Also tried activating different themes after changing the permissions. Did not work. I then changed the permissions back to 755.

From your old Forum I read that maybe memory was a problem. I installed “WP-Memory-Usage” and can report that …

PHP Version : 5.4.20 / 64Bit OS
Memory limit : 128 MB
Memory usage : 22.92 MB

====================================
extra details …

I think the last thing I had tried to do was to activate a customized version of the vortex theme which did not work – so I re-activated one of the default calendar themes, which did not work – and none of the other themes did either. I tried deleting my custom calendar theme. I tried de-activating plugin, deleting the entire all-in-one-calendar plugin directory and re-installing via uploading zip (I thought maybe this was an apache permissions issue). Still will not render CSS!!!

Then I tried everything else you can read above.
