 * Hi,
 * I recently switched my WordPress from App engine PHP7 standard to flex. Since
   then, as far as I can see, WordPress doesn’t generate thumbnails/image sets when
   I upload new media. I get the warning:
 * `Warning: chmod(): Google\Cloud\Storage\StreamWrapper::stream_metadata is not
   implemented! in /app/public/wp-admin/includes/file.php on line 925 964`
 * In my logs I find `NOTICE: PHP message: Stream wrappers are not allowed.`
 * No images (but the uploaded one) get created anymore in my bucket.
 * I’m running WordPress 5.5.1 and GCS-Plugin 0.1.6. I activated the PHP extensions
   exif and imagick, didn’t help. Also deactivating all other plugins didn’t help.
 * Thank you!
 * Best regards,
    Wolfram

 * Can you please try with WordPress 5.6 (currently in beta – see [https://make.wordpress.org/core/5-6/](https://make.wordpress.org/core/5-6/))
   and the imagick extension?
 * There is a [known issue](https://core.trac.wordpress.org/ticket/42663) with earlier
   versions of wordpress-core. You may still see the chmod warning, but the thumbnails
   should work.

 * Hello,
 * the problem still exists in the latest version (5.6) of wordpress.
    It also makes
   no difference whether you use gd or imagick.
 * chmod(): Google\Cloud\Storage\StreamWrapper::stream_metadata is not implemented!
