Thumbnails with wrong CHMOD Permission

I have the same problem! Please advice! This is killing me!

This is really annoying me as well, It’s time sensitive as my host will be deleted my account shortly as I’ve just moved to a new server. Main images backup fine, thumbnails “Permission Denied” even inside Plesk!

This is what you need to do to get permission back, create a file called whatever-you-want.php in the same folder as all the thumbnails and copy this code into it:

<?php
// Note that !== did not exist until 4.0.0-RC2

if ($handle = opendir('./')) {
    echo "Directory handle: $handle\n";
    echo "Files:\n";

    /* This is the correct way to loop over the directory. */
    while (false !== ($file = readdir($handle))) {
        if(chmod($file, 0755)) echo "\n".$file." - CHMOD to 0755 a success<br/>";
        else echo "\n".$file." - CHMOD to 0755 a failiure<br/>";
    }

    closedir($handle);
}
?>

It’s a bit of a fudge but it works! I just wrote it, change 0755 to whatever permissions you want to set. Good luck!

Obviously you have to run the code by pointing your browser to https://www.yourdomain.com/wp-content/uploads/whatever-you-want.php just make sure you point to the right place.

I made the whole thing better and posted it in a zip file on my website, you can get it here: WordPress Eats Thumbnails

Hello again! Chris recently emailed me with a comment, my script doesn’t scan sub-directories and fix the issue as well. Sorry about this, I could add this in but the next version of wp is bound to fix this highlighted problem and sadly I do not have enough time. Instead, please just drag the script in the sub-directories and run it from there.

I had the same problem and fixed it like this
