Updating PHP version reverts to default

Hi Guys,
I've encountered and error with ISPconfig when updating a site from the default PHP version to another version.
When revisiting the website entry t in ISPconfig I note the version has reverted to default and my site will return a 503 error as the default version is deprecated.
Hoping for some clarity.

 

Hi Till
Thank you for your prompt feedback.
Yes I was logged in as admin.
To further elaborate the error presents as follows:
-> Update PHP version to 8.1
-> Confirming the update via phpinfo file
-> At any given time a return the website settings in ISP config not even changing the PHP settings i.e prehaps just looking at the backups section
-> The site will then immediately return 503
-> I can bring the site back by reupdating the PHP version to 8.1 ( I note at this time the PHP version is set back to default)
Hope this might abit more detail, thank you for your help.

 

Hi Till,
My version is ISPConfig 3.1.15p3.
I have 4 sub-servers link to my primary instance but the primary server runs Ubuntu 20.
No manual alterations to my knowledge, this a server setup that was hand over to me.

 

Please do this:

Notice the default PHP must remain what is provided by the OS. Additional php versions can be installed for use in websites.

 

And please also check https://www.howtoforge.com/ispconfig-php-ubuntu/ to ensure that you had installed multiple php correctly and to fix your server with default php.

I noted that Ubuntu server did have such behaviour of changing default php upon certain php updates so I did share some script to fix such change, if it happened, automatically. Do read about it here: https://forum.howtoforge.com/threads/monitor-os-default-php-and-restore-if-changed.83288/
