Hello,
Thanks for your quick reply.
Below are the steps I have done:
I have installed the following plugin on each sites of the network + the main sites:
https://ww.wp.xz.cn/plugins/code-snippets/
I have added a new PHP snippets called REST API WPML with the following code:
add_filter( 'rest_url', 'wpml_permalink_filter' );
Then I came back to the settings of your plugins and tried to generate images again.
It returned the following errors again:
12:08:54 - An error occurred while connecting to REST API. Please try again.
404 - (https://www.hexaconcil.net/en/wp-json/webp-converter/v1/paths-fd9d9aacdb)
Let me know,
Thanks
