I have just updated and verified my X theme, then went to update the Cornerstone plugin and the website abruptly broke. Every page including my wp-admin gives me HTTP ERROR 500.
EDIT: I have contacted my domain host and they fixed the problem by disabling the plugin. However, I am now wary of activating Cornerstone - how can I activate and use Cornerstone without running into the same problem again? I need it to be activated, my website was built using it and now it is just a pile of code.
EDIT 2: After now uninstalling and attempted to reinstall Cornerstone, the website is broken again. This is ridiculous, and I need my website functional again. My domain provider says there is an issue with the plugin, please please help!
