pfSense

On upgrading (from the previous latest version to 2.4.5) the system came up and then reported an php error in all of the dashbord windows. the dashboard became unresponsive.
On accessing the console a php error (such as the one below) was being generated in the midst of the text menu.

I opened a shell and symbolic linked the previous directory (/usr/local/lib/php/20131226) (which was fortunately still there) to the missing one (20170718)
This has returned fucntionality.

However this will cause real problems for users that are unable to debug such a situation.

I am still without a valid /usr/local/lib/php/20170718 an do not hnow the impact that will have.

Can you suggest the package to install that contains the valid /usr/local/lib/php/20170718 directory please.

Errors below and the full upgrade log is included.
