File storage issues for nunil_script.rbx

Hi @kojis this code should check if the upload dir is writable, and disable persitence if it is not:

https://github.com/MocioF/No-unsafe-inline/blob/3d9f2c47493500277a8d54e94c8e8e4c23903a57/src/Nunil_Knn_Trainer.php#L168

Can you help me to understand if on WPVIP this function returns true or false?

Hello @mociofiletto

I can confirm that the upload directory is _not writable_ on WPVIP hosting.

This information seems helpful:
https://wpml.org/errata/wordpress-vip-hosting/

Unfortunately, despite the fact that it is not writable, the check_write_permission function you cited, does in fact return true which generates the error.

I have found that forcing this function to return false, allows the plugin to function on WPVIP with an additional minor change:

$mu_dir    = trailingslashit( WP_CONTENT_DIR ) . 'client-mu-plugins';

Must be changed to:

    $mu_dir = '/client-mu-plugins';

in two locations within
/src/Nunil_Manage_Muplugin.php

and the muplugin must be specifically committed to version control and deployed during the build pipeline process.
