Upgraded to Pro => Fatal error due to Cornerstone

[Joppedi]

I have read some topics about similar errors (https://theme.co/apex/forum/t/fatal-error-when-editing-in-pro/36715) but can´t solve problem.
I have first tried X and upgraded to Pro version 2.1.6 using WordPress theme uploader.
As soon I try to save any of theme options I get error, both frontend and admin:
“Fatal error: require_once(): Failed opening required ‘/home/munkaweb/public_html/kunder/wp/wp-content/themes/pro/cornerstone/includes/classes/styling/class-font-manager.php’ (include_path=’.:/opt/alt/php56/usr/share/pear:/opt/alt/php56/usr/share/php’) in /home/munkaweb/public_html/kunder/wp/wp-content/themes/pro/cornerstone/includes/cornerstone-plugin.php on line 105”

I have:

• No other plugins but Wordfence which works fine with X. Before upgrading to Pro I deactivated and deleted Cornerstone.
• Changed wp-config with:
  define( ‘WP_MEMORY_LIMIT’, ‘512M’ );
  define( ‘WP_MAX_MEMORY_LIMIT’, ‘1024M’ );
• Now I have define(‘WP_DEBUG’, true); to debug
• server first used PHP-version 5.3. I upgraded to version 5.6 and then to version 7.0 but didn’t solve problem.

Hi there,

If you are using Pro, you do not need to install and enable Cornerstone separately as it is already native to Pro as the Pro builder. Kindly double check if you have Cornerstone uninstalled.

If you have it clear already, please check if you have uploaded the complete Pro theme files and have the file permission correct.

Hope this helps.

Permissions/chmod was the answer! Now it works
1.I had already deleted standalone Cornerstone for X, so that was not the solution.
2. I now uploaded all files in Pro-theme, manually with ftp: not the solution.
3. Checked permissions for pro/cornerstone/includes/classes/styling/class-font-manager.php. It was blank. Changed to 644 and now theme with cornerstone works.

Initial error also mentioned /pro/cornerstone/includes/cornerstone-plugin.php but when I checked permission it had 644.
Hope you can fix install-process of theme so this will not happen for others in future.

Thanks for support!
