Updating cornerstone version


I have a problem with updating my cornerstone (X Themeco) it is indicating this :
This Cornerstone license is ​not validated​ & An error occurred while updating Cornerstone: X is not validated. Validate X to enable automatic updates.

I also did validate the as it indicated but it is still showing the error. also this error is interfering with certain plugins such as the Revolution Slider which indicating this when activating it:
Plugin could not be activated because it triggered a fatal error.

Thanks in advance

Hi There @scope

Thanks for writing in! First of all, check some of your server configurations below to avoid incompatibility issues.

  1. We recommend PHP version 5.6.x or later.
  2. Make sure that PHP cURL extension is enabled on your server
  3. Check your PHP memory limit and increase if necessary by following our guide here (https://theme.co/apex/forum/t/troubleshooting-increasing-php-memory-limit/16935).
    Further, check the following troubleshooting guide here (https://theme.co/apex/forum/t/troubleshooting-validation-connection-issues/201).

Also check our version information here (https://theme.co/apex/forum/t/troubleshooting-version-compatibility/195) and compare it with your current versions. If you’re few versions behind, I would suggest you to re-install X theme and Cornerstone by downloading the latest version. You can follow our manual update guide here (https://theme.co/apex/forum/t/setup-updating-your-themes-and-plugins/62).

If you’re still having any issues, provide us with your login credentials in a secure note to check your issue further.
