error 0024, get_page_permastruct fatal error, conflict with fastest-cache ?

Hello,

We’re trying your plugin, it passed all of our test in staging but instantly broke all the admin side of the production (including wp-post.php and wp-ajax.php so this impact some of the front too) after deploy. Please note I’m a web developer and I’m used to work with wordpress among other.

We have a bug catching system so I can provide you some information, firstly here is the stacktrace :

The plugin is up-to-date, as well as WordPress, php, and the system :
`
runtimeVersions
{
“php”: “7.3.10-1+ubuntu18.04.1+deb.sury.org+1”,
“wordpress”: “5.4.1”
}
`

Your custom Logger stored (2 312 times…) the following under the ‘qmn_log’ custom post type :
Error 0024 : Usage tracker failed due to following reason: cURL error 6: Could not resolve host: data.quizandsurveymaster.com
I’m not sure it’s a related. I don’t really understand why their is anything to track on the plugin activation anyway.. I curl this url locally in my machin and I have the same error by the way.

It seems to be an incompatibility between your Log custom post type creation because the code not working and causing the fatal error on wp-fastest-cache side is the folowing (this is only WordPress code) :

`
if($page_for_posts_id = get_option(‘page_for_posts’)){
$page_for_posts_permalink = urldecode(get_permalink($page_for_posts_id));
}
`

Are-you aware of this issue ? Are-you working on it or have-you a work around ?
