Fatal Error on Cornerstone Update

[lhd333]

My site is completely messed up.

I reinstalled X. Then reinstalled cornerstone.

Then updated cornerstone and got this message:

Unpacking the update…

Installing the latest version…

Removing the old version of the plugin…

Plugin updated successfully.

Plugin failed to reactivate due to a fatal error.

Fatal error : Call to undefined method ReflectionParameter::getType() in /home/MYSITE/public_html/wp-content/plugins/cornerstone/includes/classes/Plugin.php on line 105

What to do?

Hi @lhd333,

Thanks for reaching out!

I suggest that you update your PHP version to 7.4 and up then it will be fixed your issue.

Hope that helps.

Thank you.

PHP version to 7.4

I’ve just done this. Can’t install/activate cornerstone because of fatal error still.

Hi @lhd333,

The WordPress itself says the site is running an outdated version of PHP (5.6.40) (see Tools > Site Health)

I reinstalled X version 7.2.3 and Cornerstone 4.2.3 on the site so it’s going up and running.

But please update your PHP version to 7.4 first, before you update X and Cornerstone to the latest version.

Please contact your hosting on how you can update PHP version.

Thanks,
