Google Devtool keeps blocking the dhtmlx.css
This appears to be a client-side browser issue, not a code issue. It looks like that’s something usually done inadvertently by the user. See this post on StackOverflow for more information.
You should be able to find the blocked request on the Network tab of DevTools and right-click it, then tell it to unblock the request.
yes I also saw that Stack Overflow and I have no know how it the user is accidentally blocking
Also when I go into the dev toolbox select the css and right click “block” is the only option there is no “unblock”
