Fatal Error

@kiandept

Unfortunately, I cannot reproduce the issue, it works on my end. I have already tested it on local, shared hosting, VPS, and dedicated servers.

Could you please provide more details about the error? Check the error_log file on your server for relevant entries.

Also, please enable WordPress debugging and share the debug output so we can see what happened:

@kiandept Thank you for sharing the debug info. this issue is likely caused by something specific in environment.

Could you please check the following:

• File permissions: Ensure all plugin files and folders have proper read permissions for the web server (usually 644 for files and 755 for folders).
• Clear PHP caches: If your server uses OPCache or any PHP cache, please clear it or restart your PHP process.
• PHP version: Confirm your PHP version is supported (7.4+ or 8.x).

Also, if possible, please help us gather more detailed debugging info by doing the following:

1. Open the file: /secure-passkeys/src/core/secure-passkeys-autoloader.php

2. Find

private function get_class_file(string $class): string
{
    $class_file = strtolower(str_replace('_', '-', $class));
    $class_file = str_replace('\\', DIRECTORY_SEPARATOR, $class_file);
    $class_file = str_replace(SECURE_PASSKEYS_PLUGIN_BASENAME . '/', '', $class_file);

    return SECURE_PASSKEYS_PLUGIN_DIR . '/src/' . $class_file . '.php';
}

3. Replace it with:

   private function get_class_file(string $class): string
    {
        $logs = [];
        $logs[] = SECURE_PASSKEYS_PLUGIN_FILE;
        $logs[] = SECURE_PASSKEYS_PLUGIN_DIR;
        $logs[] = DIRECTORY_SEPARATOR;
        $logs[] = $class;

        $class_file = strtolower(str_replace('_', '-', $class));
        $class_file = str_replace('\\', DIRECTORY_SEPARATOR, $class_file);
        $class_file = str_replace(SECURE_PASSKEYS_PLUGIN_BASENAME . '/', '', $class_file);

        $logs[] = $class_file;
        $logs[] = SECURE_PASSKEYS_PLUGIN_DIR . '/src/' . $class_file . '.php';
        $logs[] = file_exists(SECURE_PASSKEYS_PLUGIN_DIR . '/src/' . $class_file . '.php');

  
        if(strpos(strtolower($class),'application') !== false){
            error_log(print_r($logs,true),3,__DIR__.'/logs.log');
        }

        return SECURE_PASSKEYS_PLUGIN_DIR . '/src/' . $class_file . '.php';
    }

4. Then refresh the site once to generate the log file.

This will create a logs.log file inside /secure-passkeys/src/core/. Please share the contents of that log file with me — it will help identify exactly how your environment is resolving paths and separators.

After that, you can remove this debug code to keep things clean and I hope this will give me full clarification of your issue.

@kiandept Yes, I’m aware it’s running locally on Windows, which is why I asked you to log the autoloader to help me identify the issue.
Open: /secure-passkeys/src/core/secure-passkeys-autoloader.php

Replace

private function get_class_file(string $class): string
{
    $class_file = strtolower(str_replace('_', '-', $class));
    $class_file = str_replace('\\', DIRECTORY_SEPARATOR, $class_file);
    $class_file = str_replace(SECURE_PASSKEYS_PLUGIN_BASENAME . '/', '', $class_file);

    return SECURE_PASSKEYS_PLUGIN_DIR . '/src/' . $class_file . '.php';
}

With:

private function get_class_file(string $class): string
{
    $class_file = strtolower(str_replace('_', '-', $class));
    $class_file = str_replace('\\', '/', $class_file);
    $basename = strtolower(str_replace('\\', '/', SECURE_PASSKEYS_PLUGIN_BASENAME . '/'));

    if (strpos($class_file, $basename) === 0) {
        $class_file = substr($class_file, strlen($basename));
    }

    $class_file = str_replace('/', DIRECTORY_SEPARATOR, $class_file);

    return SECURE_PASSKEYS_PLUGIN_DIR . DIRECTORY_SEPARATOR . 'src' . DIRECTORY_SEPARATOR . $class_file . '.php';
}

Finally, please try this one, it should resolve the issue, if it does, please confirm.

@kiandept

Great, Please stay tuned, the next release is coming soon.
