Error in the wordpress admin "failed to open stream: No such file or directory" - how to fix?

Question

local server

Hello! I have a wordpress site with the WP Hide Post plugin installed . There is a need to transfer the site to a new hosting, but I decided to play it safe and check its performance after importing it to a local Open Server .
And not in vain - at the top of the admin panel I get the following errors:

fopen(C:\OSPanel\domains\localhost\site/wp-content/plugins/C:\OSPanel\domains\localhost\site\wp-content\plugins\wp-hide-post\wp-hide-post.php) : failed to open stream: No such file or directory in
in C:\OSPanel\domains\localhost\site\wp-includes\functions.php on line 4848
Warning: fread() expects parameter 1 to be resource, boolean given in C :\OSPanel\domains\localhost\site\wp-includes\functions.php on line 4851
Warning: fclose() expects parameter 1 to be resource, boolean given in C:\OSPanel\domains\localhost\site\wp-includes\ functions.php on line 4854

Pointed to by the following lines of code in functions.php

/**
 * Retrieve metadata from a file.
 *
 * Searches for metadata in the first 8kiB of a file, such as a plugin or theme.
 * Each piece of metadata must be on its own line. Fields can not span multiple
 * lines, the value will get cut at the end of the first line.
 *
 * If the file data is not within that first 8kiB, then the author should correct
 * their plugin file and move the data headers to the top.

 * @param string $file            Path to the file.
 * @param array  $default_headers List of headers, in the format array('HeaderKey' => 'Header Name').

 */
function get_file_data( $file, $default_headers, $context = '' ) {
  // We don't need to write to the file, so just open for reading.
  $fp = fopen( $file, 'r' );

  // Pull only the first 8kiB of the file in.
  $file_data = fread( $fp, 8192 );

  // PHP will close file handle, but we are good citizens.
  fclose( $fp );

  // Make sure we catch CR-only line endings.
  $file_data = str_replace( "\r", "\n", $file_data );
...
}

How can you fix them? If I deactivate the plugin, the error disappears. How can I fix errors in an included plugin?
Or is this a bug only because of the local server? Cleared the cache.

Answer 1

Well, the first error says that the file on such and such a path was not found.
Do you have any questions about the path to the file? Calls me.
I would insert something before the fopen function to see the contents of the $file variable.
For example
This will create a log.log file in the folder with the file and output the contents of this variable there.
Well, you have to look further.
