I'm guessing 3.1.x, since wp-includes/functions.php has an fopen() on line 4284 (whereas WP 3.2 has only a line break).<br><br>The WP function calling fopen() is get_file_data(). Does your theme call this function directly?<br>
<br>Here's the code:<br><br>/**<br> * Retrieve metadata from a file.<br> *<br> * Searches for metadata in the first 8kiB of a file, such as a plugin or theme.<br> * Each piece of metadata must be on its own line. Fields can not span multple<br>
* lines, the value will get cut at the end of the first line.<br> *<br> * If the file data is not within that first 8kiB, then the author should correct<br> * their plugin file and move the data headers to the top.<br> *<br>
* @see <a href="http://codex.wordpress.org/File_Header">http://codex.wordpress.org/File_Header</a><br> *<br> * @since 2.9.0<br> * @param string $file Path to the file<br> * @param array $default_headers List of headers, in the format array('HeaderKey' => 'Header Name')<br>
* @param string $context If specified adds filter hook "extra_{$context}_headers"<br> */<br>function get_file_data( $file, $default_headers, $context = '' ) {<br> // We don't need to write to the file, so just open for reading.<br>
<span style="background-color: rgb(255, 204, 204);">$fp = fopen( $file, 'r' );</span><br><br> // Pull only the first 8kiB of the file in.<br> $file_data = fread( $fp, 8192 );<br><br> // PHP will close file handle, but we are good citizens.<br>
fclose( $fp );<br><br> if ( $context != '' ) {<br> $extra_headers = apply_filters( "extra_{$context}_headers", array() );<br><br> $extra_headers = array_flip( $extra_headers );<br> foreach( $extra_headers as $key=>$value ) {<br>

<br>The errors on the second user's site were the same. The user has currently deactivated the theme and has an under construction page displayed.

This would be a lot easier to diagnose if you could provide information like:<br><ul><li>hosting environment</li><li>php.ini settings<br></li><li>full text of error messages</li><li>what types of pages/requests generate the errors<br>
</li></ul>If the errors are only showing in 2:10,000 installations, then there's a good chance that those 2 users have an unusual server configuration or file/URL structure.

Greetings All Concerned ...<br><br>I have a theme on the Repository--Wordsmith Anvil--which does not use fopen, fgets or freads functions. It has been downloaded close to 10,000 times and I have just received a comment from the second user who is receiving errors referencing "failed to open stream: no suitable wrapper could be found in ...", or "supplied argument is not a valid stream resource in ..." with this theme. The errors all point to various lines of wp-includes/functions.php, except one file reference to the theme default css file, style.css. The first user told me they disabled all plugins. Also, they performed a fresh WordPress install and did not see the errors using TwentyTen and a number of other themes. The second user who contacted me yesterday told me they do not have any plugins installed and when they activated the Wordsmith Anvil theme, these errors display at the top of the page. <br>
<br>Knowing that these functions are not used in this theme; yet the errors seem to be theme specific, and each user experiencing these errors have WordPress installations hosted on entirely different servers I am more uncertain as to why these errors are being displayed. I was hoping someone on this list may have experienced this with another theme and could shed some light on why these errors would occur when the theme does not use those functions. In fact, if these functions had been used in my theme, I am fairly certain it would not have been approved anyway. <br>
<br>Otto, Nathan, Chip, Justin, Emil, Cais, etc ... any thoughts or feedback on this. I would like to address this so that users in the future do not see these errors.<br><br clear="all"><b style="color:rgb(0, 102, 0)"><span style="font-family:trebuchet ms,sans-serif">Best Regards</span><br style="font-family:trebuchet ms,sans-serif">
