I copied the blog folder over and deleted its entirety from the plugins section and was able to pull my site back up. Would still like to know whats going on with this..
this is line 198
  OW::getEventManager()->bind(BOL_ContentService::EVENT_COLLECT_TYPES, array($this, "onCollectTypes"));

I had a copy of the old blog. I deleted the new blog with the new update that apparently is breaking the site. I've copied the old blog files back over and it seems to be working. Please keep me updated or posted on this new blog updated.

Have you updated platform first and then plugins?

Go here: /ow_system_plugins/base/bol/ and make sure there's a file content_service.php

You need to disable blog plugins via phpmyadmin

Go to ow_base_plugins table locate Blogs row and put 0 in the column isActive

You will have an access to the admin panel. You will need to do the update of the platform. Then update the rest of the plugins. 

For the future reference, always do update of the platform first, then plugins. Make a backup beforehand. 

Thank you Ross, i'll try this later.  Rebecca, if you need a copy of the old blog folder,I can send you  a copy.. In the meantime I suggest SAVING your current Blog folder to your desktop. Then completely deleting the blog folder on the server via FTP. That should help you get your site back up and going. Go ahead and update the Oxwall site itself, then drop the folder back into the plugins. That should work for ya! If not, just shoot me a  message and i'll send ya my copy of the old blog files which are the most recent ones BEFORE this current update.  Be sure to back up your site before you Update ANYTHING just incase this happens again.

Cheerio

Or you can do it the way Ross suggested :) He's the expert after all! :)

Rebecca, be more attentive, I said via phpmyadmin in your Database
