Invalid argument supplied foreach()

Thanks for the bug report!

You can try deactivating cwebp and see if it starts working.

But the error indicates that the configuration file is invalid (it is generated when you save options in WebP Express). Can you post wp-content/webp-express/wod-options.json here? and also wp-content/webp-express/config.json – thanks!

Hi and thanks for that quick answer ?? !

Even with cwebp deactivated, it doesn’t work.

Here are the files you asked for:

Thank you !

hm, options looks fine, actually. I’m thinking that perhaps the options aren’t passed correctly to webp convert. The passing happens in plugins/webp-express/wod/webp-on-demand.php. Before debugging this file, however, try to add ?debug after an image url. This should trigger delivering a report instead of an image.

Hi!

?debug at the end of an image url just displays the image for me :s

Ok, you are probably in “CDN friendly” mode. Anyway, I wasn’t thinking. The Bulk conversion does not pass the option through webp-on-demand.php. The action rather happens in lib/classes/BulkConvert.php and lib/classes/Convert.php. I’m going to have to wait for this till after the weekend. But you could try to add debug lib/classes/Convert.php. For example, try to see if $config contains the config file in the beginning of the convertFile() function. You can write to the error-log with the error_log() function. And serialize $config with print_r($config, true);. Combined: error_log(print_r($config, true));
