Hi,
After the recent updates Cornerstone and the X Theme, my website will no longer load. It just shows a white screen. When I remove Cornerstone as a plugin the website loads perfectly fine. I have even made Cornerstone the only plugin and when it is the only plugin active my website only shows a blank page. My website is wdwchronicle.com.
Any help would be greatly appreciated!
thank you!

Hi There,
It might be the Cornerstone plugin was corrupted while updating.
I’ve already fixed it.
Everything should be fine now.
Cheers!
Thank you for looking into this. Unfortunately, I get the code below when trying to log in.
Warning: require_once(/home/wdwchron/public_html/wp-content/plugins/cornerstone/includes/classes/styling/class-font-manager.php): failed to open stream: Permission denied in /home/wdwchron/public_html/wp-content/plugins/cornerstone/includes/cornerstone-plugin.php on line 105

Hello @WDWChronicle,
Thanks for asking. 
Yes, on front end and upon login I could see the error messages. To resolve the same, I used Filezilla and under /wp-content/plugins/ directory I renamed the Cornerstone folder. After that I reloaded the page and website was working fine. After that I went and clicked on X menu to automatically download Cornerstone. Although Cornerstone was downloaded, upon reloading the page I could see the same error message. I repeated the earlier steps using Filezilla. After that I downloaded a fresh copy of Cornerstone and manually uploaded installed Cornerstone from Plugins > Add New. However, upon reloading the page I am getting the same error message.
At this point of time I am not able to pin point the cause of the problem but most likely it’s permission issue that’s causing the problem. You can take a look at following article:
http://www.wpbeginner.com/wp-tutorials/how-to-fix-the-wordpress-failed-to-open-stream-error/
To confirm wether or not it’s hosting related issue I would suggest you to please copy the website to a local or staging environment and see if this error message shows up. We want to make sure that there are no environmental factors causing the issue here.
Get back to us with the result of the test. Thank you.
Popping in with an update. I believe I have it fixed!
The class-font-manager.php file in the Cornerstone plugin had 0 permissions set and would not allow for permissions to be changed in any way. So, I extracted the class-font-manager.php file from my X-Theme download, deleted the class-font-manager.php file and replaced it with the extracted file that had correct permissions.
Everything seems to be working great now. If it doesn’t stick I will provide another update.
Thanks for all your help!
UPDATE #2
With every update the new Cornerstone plugin would break the site. After doing some more digging around Imunify360 was quarantining the class-font-manager.php file as it was labeling it malware. I took it off the quarantine list and everything working properly now.
