Hi, @mateuszgbiorczyk
I have the same problem and the REST API isn’t disabled on the website. I’m getting this error (in the console):
jquery.js?ver=1.12.4-wp:4 POST https://bareminds.local/wp-json/webp-converter/v1/paths?_wpnonce=93acac81b7 403
send @ jquery.js?ver=1.12.4-wp:4
ajax @ jquery.js?ver=1.12.4-wp:4
value @ scripts.js?ver=1.0.5:1
value @ scripts.js?ver=1.0.5:1
