OPcache is not enabled on this site. Main plugin features are disabled.

Hello @dleigh!

The way OPcache Manager verify if OPcache is “usable” for itself is by verifying the standard PHP functions opcache_get_status() and opcache_get_configuration() exist. If it says “OPcache is not enabled on this site[…]” it’s because something in the PHP configuration disable one or both of these functions.

It’s a pretty common thing with many hosting providers to have these functions disabled. Can you verify if yours disabled one of them?

Hello @pierrelannoy,

So the OpCache implementation at my host (IONOS) is Zend. Here’s what phpinfo tells me about the Zend OpCache parameters currently:

Opcode Caching? Up and Running
Optimization? Enabled
SHM Cache? Disabled
File Cache? Enabled
JIT? Disabled
Startup? OK?

opcache.blacklist_filename no value no value

opcache.use_cwd On On
opcache.validate_permission Off Off
opcache.validate_root Off Off
opcache.validate_timestamps On On

Other than adjusting the directives for Zend OpCache in the php.ini file, I’m not sure what I can do. Do any of those directives correspond to opcache_get_status() and opcache_get_configuration()?

Thanks!

Hello?@dleigh!

If you want to verify if these(or one of these) function(s) is disabled, you have to search for disable_functions = … in php.ini. Or maybe in the managing panel (I don’t know which one is used by Ionos but in Plesk, for example, there is a field to set disabled php functions).

As I don’t know Ionos, I think you have to ask them…

So these functions would be listed just as you named them?

opcache_get_status() and opcache_get_configuration()

Our php.ini is very short:

memory_limit = 1024M
upload_max_filesize = 128M
error_reporting = E_ALL | E_STRICT;
log_errors = On;
display_errors = Off;
error_log = /***/htdocs/php-errors.log;
opcache.file_cache=/***/htdocs/.opcache;
zend_extension=opcache.so;
opcache.enable=1;
opcache.memory_consumption=128;
opcache.interned_strings_buffer=8;
opcache.max_accelerated_files=26000;
opcache.revalidate_freq=180;
opcache.fast_shutdown=0;
opcache.enable_cli=0;
opcache.revalidate_path=0;
opcache.validate_timestamps=1;
opcache.max_file_size=0;
opcache.file_cache_only=1;

So there’s no “disable_functions” in there. In my phpinfo, the disable_functions is empty. Anything that mentions OpCache in the phpinfo output is under the Zend OpCache section that I already posted.

IONOS, unfortunately, does not give you a place where you can turn on and off PHP modules, like in cPanel, for instance – at least not on OUR hosting plan. So if I ask their support what to turn on, am I asking them to turn on?

opcache_get_status() and opcache_get_configuration()

Yes, that’s YOUR php.ini. In fact, the actual configuration is done by merging many php.ini (including yours). What you have to observe is the “result” of this merge… You can do it with phpinfo() function.

If you want a “shortcut”, you can do that with a plugin like this one. After activating it, just verify strings like disable_functions and disable_classes. It would be a first insight…

Well, like I just said:

In my phpinfo, the disable_functions is empty. Anything that mentions OpCache in the phpinfo output is under the Zend OpCache section that I already posted.

So if there is something else I can check in the phpinfo, I have it all. Just let me know what to look for, please.

Hey @dleigh Did you get this solved? I have a client with IONOS and am running into the same problem.

I’m sorry to say that I did not, and I’ve recently moved the client to another hosting company. Personally, I hope that I don’t ever have to support someone on IONOS again.
