Hi @f112

Is the following line included in the file and is it uncommented?

extension=apcu.so
3

…oh, and there must be no spaces in “apc.enable_cli = 1”.

Make sure you add it like this…

apc.enable_cli=1

@bb77 thanks for the advice.
Yes, extension=apacu.so is enabled. However, apc.enable_cli=1 was with a space … I removed the spaces, made
#phpenmod apcu
#systemctl restart apache2.service
but no result.

did you change anything else on your system, other than installing php-apcu and enabling it? Did everything work before you made these changes?

Wich package did you install exactley? Make sure php7.4-apcu is installed

Can you post your config.php? (please use “Preformated text” (the “</>” symbol) if you do so and remove all sensitive information like passwords, domain names etc…)

@bb77 thank you very much! I tried to install:
apt install php7.4-apcu
And everything turned out!
The question is resolved!
