403 in every png upload

by nickdesignz·4 years ago

This tool generates also a code which adds a src to your png, this source is a 403;

src="//www.w3.org/2000/svg%22%20viewBox=%220%200%201228%20294%22%3E%3C/svg%3E" class="attachment-full size-full lazyload"

Source is invalid which causes many 403 errors on your site.

ALSO: It’s not necessary to link to another source on a third plattform. This is just slowing down your site.

Don’t install!

Great Plugin for saving time

by rmstm·4 years ago

This plug-in will transform all your actual PNG media to WebP + automatically transform them in WebP when downloading new loud formats, in a beautiful manner. Simple in the presentation but powerful in the application. I recommend it a lot !
