PHP Notice: Undefined index: HTTP_X_FORWARDED_PROTO

usually a Notice is not a problem. Try running without the ‘; echo $?’ portion and see what happens.

The same happens.

sudo -u www-data wp ewwwio optimize all

PHP Notice:  Undefined index: HTTP_X_FORWARDED_PROTO in phar:///usr/local/bin/wp/php/wp-cli.php(23) : eval()'d code on line 7
Optimizing all with a 0 second pause between images.
Scanning, this could take a while
47 images in the Media Library have been selected (0 unoptimized), with 288 resizes (0 unoptimized).

I.e. it doesn’t find any more images than in the wordpress folder.

Ok, I think I misunderstood the problem. It isn’t necessarily that it isn’t working, but it still isn’t finding images in the folder you symlinked and entered on Folders to Optimize, correct?

Yes. Isn’t finding the extra images.

Perhaps turn on debugging, and see what shows up in ewww-image-optimizer/debug.log when you run it from wp-cli

If you can, you might also try running it as root to see if that makes any difference.

did you ever get any further on this?

Root doesn’t make a difference.

How do I enable debugging?

The very first option on the EWWW IO settings page turns on debugging.

Web, still:

Operation timed out, you may need to increase the max_execution_time for PHP

check the memory limit for php, it might need bumped up just a bit.

Tried this in https://www.ads-software.com/support/topic/ewww-as-a-separate-php-tool-to-be-run-on-whole-whm-account?replies=20#post-6691371 – unfortunately, it didn’t solve this.

do you have access to your server error logs? They should indicate why it is failing.

Fortunately, yes.

Allowed memory size of 134217728 bytes exhausted (tried to allocate 4294961842 bytes) in /var/www/blog/wp-content/plugins/ewww-image-optimizer/ewww-image-optimizer.php on line 906, referer: https://www.whonix.org/blog/wp-admin/upload.php?page=ewww-image-optimizer-bulk

That’s ~4 GB.

Well, I raise set the php limit up to that, but I am not sure that would be sane and I am wondering, if you could create an update, that would work with common php memory limits?
