Fatal error while updating plugins

[backofficeitalia]

Hi,
i have some issues with WP Tolkit for Plesk.
I installed all my websites without problems and i updatated all of them until last month.
Today, while i trying to update the plugins i get this error:
"Selected items were listed with errors:
Unable to update plug-in 'contact-form-7_5.1.7_1_', details: A critical error has occurred on your website. Find out more about debugging in WordPress. A critical error has occurred on your website."


If i update the plugin from website i have no problems.
Can you help me?
Best regards

Could you please clarify, this issue occurred on a single website, or several websites were affected?

In all websites i have installed on this server

Could you please look for error details at /var/log/plesk/panel.log file? You need to temporarily increase the logging level to 7 (debug) and turn on logging of utils exec to catch meaningful details. Section [log] of panel.ini (/usr/local/psa/admin/conf/panel.ini) should look like this:

[log]
filter.priority = 7
show.util_exec = on

Best regards,
