PHP handler name is not changed in Plesk GUI after upgrade/downgrade of OS vendor package

Symptoms

• The PHP by OS vendor was upgraded for example from 5.4.16 up to 7.2.31.
• The version of PHP by OS vendor still shows as 5.4.16 in Plesk > Tools & Settings > PHP Settings:
  

  Note: the PHP handler name is also not changed after the downgrade procedure for the PHP by OS vendor package.

Cause

This is the Plesk bug with the ID #PPPM-4764, which will be fixed in the next Plesk update releases.

Resolution

Until the bug will be fixed, apply the following workaround:

1. Log into the server via SSH.

2. Execute the command below to reread PHP handlers:

   # plesk bin php_handler –reread

3. Run the command to get list of all hanlders that belong to OS vendor:

   # plesk bin php_handler –list | grep vendor | awk {‘print $1″t”$2″t”$3″t”$4″t”$5’}

   cgi      5.4.16 by OS vendor
   fastcgi  5.4.16 by OS vendor
   fpm      5.4.16 by OS vendor
   module   5.4.16 by OS vendor

4. Rename the required handler of the PHP by OS vendor by executing the command:

   • For fastcgi:

     # plesk bin php_handler –update -id fastcgi -displayname “7.2.31 by OS vendor”

   • For fpm:

     # plesk bin php_handler –update -id fpm -displayname “7.2.31 by OS vendor”

   • For cgi:

     # plesk bin php_handler –update -id cgi -displayname “7.2.31 by OS vendor”

   • For module:

     # plesk bin php_handler –update -id module -displayname “7.2.31 by OS vendor”
