How to fix ERR_BLOCKED_BY_CLIENT (network & console)

This error usually appears when a request is blocked by something on the client side, such as Chrome developer tools or an ad-blocking extension. 

Solution:

First, check whether the error appears in Incognito mode and in another browser. Also, try disabling all browser extensions and check again. In most cases, this issue is resolved by disabling the blocking plugin or clearing the browser cache.
