Symptoms
massUpdatePanelApps task fails with the message:
Last execution output
APS Application Error:
500 Internal Server Error
Checking /var/log/pa/pvps.log, the following error is recorded for the affected subscription:
You must have PHP 5.3.2 or later to install Plesk. Update PHP and try again.
Alternatively, the error could be:
stderr: PHP Fatal error: Cannot use 'Null' as class name as it is reserved in /usr/local/aps/7329a7f9-c2d1-40c9-b008-a61f1f5c8304/vendors/zendframework/zend-log/src/Writer/Null.php on line 12
The affected VE has default PHP version higher than 7.0.
Cause
Plesk in VPS Panel APS application does not fully support PHP 7.
Resolution
Check the current path PHP binary points to:
# ls -alh /usr/bin/php
lrwxrwxrwx 1 root root 26 Feb 21 10:56 /usr/bin/php -> /opt/plesk/php/7.1/bin/php
Switch the used PHP version to PHP 5 inside the VE for the time of running the massUpdatePanelApps task:
# unlink /usr/bin/php
# ln -s /usr/bin/php5 /usr/bin/php
After running the task and confirming the instance is updated, switch it back:
# unlink /usr/bin/php
# ln -s /opt/plesk/php/7.1/bin/php /usr/bin/php
