Also: How can I get any messages from your plugin so I can at least try to debug this?

Hi,

this does not fix the problem, since it tries to match the these two strings:

C:/xampp/htdocs/wp-content/plugins
C:\xampp\htdocs\wp-content\plugins\client-dash\core\library\rbm-field-helpers\rbm-field-helpers.php

You have to normalize both strings, so this is the fix you’re looking for:

$plugin_dir = wp_normalize_path( WP_PLUGIN_DIR );
$current_file_dir = wp_normalize_path ( __FILE__ );

if ( strpos( $current_file_dir, $plugin_dir ) !== false ) {
...

I fixed the error for now. Since I’m using a Windows system and you are using string compares to prevent edge cases I run into this issue:

in “rbm-field-helpers-php”:

if ( strpos( __FILE__, WP_PLUGIN_DIR ) !== false) {
	define( 'RBM_FIELD_HELPERS_URI', plugins_url( '', __FILE__ ) );
	define( 'RBM_FIELD_HELPERS_DIR', plugin_dir_path( __FILE__ ) );		
} else {	
	$theme_dir = get_stylesheet_directory();
		
	// Relative path from the Theme Directory to the directory holding RBM FH
	$relative_from_theme_dir = dirname( str_replace( $theme_dir, '', __FILE__ ) );
		
	// Build out our Constants for DIR and URI
	// DIR could have been made using just dirname( __FILE__ ), but we needed the difference to create the URI anyway
	define( 'RBM_FIELD_HELPERS_URI', get_stylesheet_directory_uri() . $relative_from_theme_dir );
	define( 'RBM_FIELD_HELPERS_DIR', $theme_dir . $relative_from_theme_dir );
}

and this is my fix for now.

//this fixes issues when comparing the string in the next step. 
//Original result of "WP_PLUGIN_DIR" for me was C:\xampp\htdocs\wp-content/plugins" - and is being tested against a string with only "\" in it.
$alternateString = str_replace( "/", "\\", WP_PLUGIN_DIR);

if ( strpos( __FILE__, WP_PLUGIN_DIR ) !== false || strpos(__FILE__, $alternateString) !== false) {
	
	define( 'RBM_FIELD_HELPERS_URI', plugins_url( '', __FILE__ ) );
	define( 'RBM_FIELD_HELPERS_DIR', plugin_dir_path( __FILE__ ) );
		
} else {
		
	$theme_dir = get_stylesheet_directory();
		
	// Relative path from the Theme Directory to the directory holding RBM FH
	$relative_from_theme_dir = dirname( str_replace( $theme_dir, '', __FILE__ ) );
		
	// Build out our Constants for DIR and URI
	// DIR could have been made using just dirname( __FILE__ ), but we needed the difference to create the URI anyway
	define( 'RBM_FIELD_HELPERS_URI', get_stylesheet_directory_uri() . $relative_from_theme_dir );
	define( 'RBM_FIELD_HELPERS_DIR', $theme_dir . $relative_from_theme_dir );
		
}
