I'm seeing this error PHP Warning: Invalid argument supplied for foreach() in //plugins/Nginx-FastCGI-Cache/nginx-cache.php on line 198

And getting a 502 bad gateway error along with upstream sent too big header while reading response

This is my conf for fastcgi which I thought was related

        fastcgi_buffers 16 16k;
        fastcgi_buffer_size 32k;
        fastcgi_cache_valid 60m;
        proxy_buffer_size   128k;
        proxy_buffers   4 256k;
        proxy_busy_buffers_size   256k;

Any suggestions greatly appreciated.

Getting this error Filesystem API could not be initialized.

however i can upload plugins, update core, theme etc without having to supply login credentials so i dont think thats the cause.

I have the path specified as /var/cache/nginx and both have access by www-data user

When using wp-cron, events does not always trigger a cache purge i.e save_post. I got an error message saying request_filesystem_credentials is not defined in nginx-cache.php.

Is there any way for me to edit the plugin files such that I can add the purge option to the wordpress admin bar node for site editors (or people with a specific role) as well. At present only admins are able to access it if I'm not wrong.

@tillkruss Thanks for this great plugin.

More of a Feature request than an issue.

Do you have plans to make this plugin more multiple network friendly? Mainly moving the setup to the Network admin (Setting would be a good place) instead of individual sites (tools)?

Again, Thanks for the great plugin

Hi,

I'm trying to use nginx_cache_purge_actions filter to register additional actions that should flush Nginx cache, but I noticed that this filter is applied right when plugin is loaded, so there's no way how to use this filter from (child) theme.

I understand this filter should be applied early, so one can register actions that are invoked early, but I would say running this filter in after_setup_theme hook should be early enough and would allow to use the filter from within themes.

If you're fine with my suggestion, I can make a pull request.

I tried adding add_option('nginx_cache_path', '/run/nginx-cache'); in several places, but could not add that option. Also setting 'nginx_auto_purge' to '1' automatically would be cool.

I'd really like to automate this and have little to no knowledge of PHP. Any help will be appreciated!

The plugin works super perfectly, so first thank you for making it! I use WP-PostViews plugin to count post views and it can use Ajax to count views on cached pages, however it uses Ajax only if the WP_CACHE is defined. In short, if it acknowledges that you're "using" a caching plugin, it uses Ajax to count the views. You can see another user noticed this: https://wordpress.org/support/topic/server-side-cache-not-working/

There may be other plugins that check for WP_CACHE, do you think it would be a good addition to somehow set WP_CACHE to true when the plugin is loaded?

Hi there,

I'm getting the following error:

Cache could not be purged. Filesystem API could not be initialized.

Nothing is appearing in the nginx error log. Any idea what's happening/how to debug?

Thanks

"Automatically flush the cache when content changes" checkbox isn't working.

I installed, activated, and set 'Cache Zone Path' plugin setting. Opened a given page in chrome incognito, then updated such page in wp-admin, then reloaded such page in chrome incognito. A MISS ocurred.

So the plugin is emptying the cache, just regardless of that setting.

Whenever I do anything in my site, like add a post I get redirected to a whitescreen asking for FTP credentials.

This only happens in 4.6, possibly related to
