[Cloudflare] ERROR: [CLIENT API] Array

[janvitos]

Hi,

I noticed that Cloudflare now throws an error in the nginx error log whenever I publish or update a post.

Here's the exact error log:

2020/07/01 11:43:45 [error] 3849136#3849136: *1285712 FastCGI sent in stderr: "PHP message: [Cloudflare] ERROR: [CLIENT API] Array

I have removed my email, website name and auth key from the logs, but I know the values are correct.

Thanks.

I am seeing this too

To add to this....

On the 30th June CF introduced a 30 url limit to purge requests (https://api.cloudflare.com/#zone-purge-files-by-url). Currently the plugin makes no provision for that limit and by and large fails relatively silently. We've put a temporary fix on our sites by removing http urls using the purge filter but in a https site it is relatively easy to hit the 30 purge limit if a post contains 5 or so terms.

Thanks for patience. There was an unfortunate coincidence of two things:

• Extended number of URLs purged on content update Purge attachment URLs #208
• Cache team separately reduced number of allowed URLs in single Cache Purge request

Release 3.5.1 contains the fix. Apologies for the trouble! 🙇‍♂️

Hi,

Thank you so much @gramorris for those details.

What I did to fix this issue is removing or commenting from /public/wp-content/plugins/cloudflare/src/WordPress/Hooks.php on line 236, the following:

// Purge https and http URLs (Line 235)
//if (function_exists('force_ssl_admin') && force_ssl_admin()) {
//    $listofurls = array_merge($listofurls, str_replace('https://', 'http://', $listofurls));
//} elseif (!is_ssl() && function_exists('force_ssl_content') && force_ssl_content()) {
//    $listofurls = array_merge($listofurls, str_replace('http://', 'https://', $listofurls));
//}

NOTE:

• If the site is using force_ssl_admin, force_ssl_content, or a plugin to redirect HTTP to HTTPS, you probably will need this.

• If the site is using native HTTPS, you won’t need this at all.

Feeds (Optional):

By default, WordPress comes with some feed types, but the most commonly used is RSS2; therefore, if you are not using RDF, RSS (1.0), or Atom feeds, you can disable them.

// Feeds (Line 217)
array_push(
    $listofurls,
    //get_bloginfo_rss('rdf_url'),
    //get_bloginfo_rss('rss_url'),
    get_bloginfo_rss('rss2_url'),
    //get_bloginfo_rss('atom_url'),
    get_bloginfo_rss('comments_rss2_url'),
    get_post_comments_feed_link($postId)
);

If you are using a third-party comments plugin like Disqus or Spot.IM, you can also disable comments_rss2_url, and also post_comments_feed_link, which is used to track the comments on a specific post.

// Feeds (Line 217)
array_push(
    $listofurls,
    get_bloginfo_rss('rss2_url')
);

Hope that helps,

Cheers.

I can confirm that the issue is fixed in 3.5.1.

Thanks for the speedy fix!
