Error: Call to undefined function trailingslashit()

I have set up open_basedir php setting to NONE, and at least connection worked, but while caching the first page, same error appeared ??

Can’t see any more, maybe you have experienced something about this and know a solution.

Hello @jonatest,

Thank you for reporting this.

Based on the provided stack trace it doesn’t look like you are running the official version of our plugin or you are not running the latest version.

Please try deleting your existing version of the plugin and install the latest 1.3.20 version.

Let us know how it goes.

Regards,

Thanks for answering!

It was last version (just checked) I installed it with the normal WordPress plugin search.
However, I’ll install an staging web to reproduce the error and let you know.

I need to bring my customers (the ones that want ultra fast results) your service but first I need to be able to test it out without issues and know how to make the right setup.

Hi @jonatest,

Did you manage to reproduce the error on the staging environment?

Regards,

Marking as solved due to inactivity.

I am facing the same issue, i am not able to access my wp-admin panel and site is only shwoing home page. To all the other pages, it shows 500error.

Hi this is Mizan from https://thegamersmall.com/, i have contact their support team and they ask for provide admin & FTP access.

we are facing the same problem but why their technical team is not working about this issue? i don’t like to share any access to anyone.

i had the same problem after downloading nitropack and activate it and conecting it with my web site i’ve got this error ??

after reading the code of the plugin nitropack in the file functions.php
there is this line
error here :
require_once $np_basePath . ‘nitropack-sdk/autoload.php’;
$np_originalRequestCookies = $_COOKIE;

i think its cookies problem or something like that… i need your help

#for your info i have no other plugins installed
