undefined function W3TC\getmypid()

Hello @moeclone

Thank you for reaching out and I am happy to help!
Can you please share when you started to see this php message, and also, have you made any changes in your environment or the plugin settings before you started seeing this?

Thanks!

Hello, @vmarko, no changes were made. Today I looked at the log and saw that the same error appears on all pages when opening them.

P.S.Another fact is that all pages have cache (x-cache: HIT) and on the product page x-cache: MISS

Hello @moeclone

Thank you for your feedback.
Not all hosting configurations allow the function getmypid().? It can be checked if the function is available or not by looking at “disable_functions” in the PHP configuration. If you are unsure about this please check with your hosting provider.

As for the ?(x-cache: HIT) this is not a W3 Total Cache header, and this means that you have another layer of caching, most likely some server side caching is active.

Thanks!

PHP does not enforce explicit restrictions on the use of certain functions
from php -i
