Hello I just installed the X theme and Cornerstone isn’t installing saying could not create directory.
Hello @realtruthmatters2010,
Thanks for asking. 
Could not create directory means there is some issue with file permission on your hosting server. I suggest you to please take a look at following articles to fix the problem:
Thanks.
I followed those instructions and it was still unable to install. I tried a manual install and it did not install. I then uninstalled the theme X and did a clean install and it would not install Cornerstone. It still says it can’t create a directory.
Hello @realtruthmatters2010,
Thanks for updating thread.
In that case please share login details (url/username/password) in a secure note for us to take a closer look.
Thanks.
I attached a secure note to the post above.
Hello there,
Please update the secure note with your FTP Host/User/Pass so we can access what files/folders to update file permissions in.
Thank you.
Hi there,
It’s because your plugins folder is missing and renamed to plugins11. I went ahead and fixed it and cornerstone is also installed.
Thanks!
Thanks so much!
You are most welcome.
