Hi there,
Both images (https://joxi.ru/nAy7VVBuk4yq7m and https://joxi.ru/4AkdbbvcVYNJ6r) are in your Media Library, so you should be able to find them there if you search for them. If this is not the case, I recommend you to contact the developer you trust or open a new thread in Fixing WordPress, as this is not a problem with our plugin.
On the other hand, if you want to know how to clear WP Fastest Cache cache, I recommend you to contact WP Fastest Cache support team.
The suggestion to use the ?nocache
parameter at the end of the URL only serves the purpose of bypassing the cache and forcing the browser to retrieve a fresh copy of a web page or resource from the server. This happens because Enable Media Replace cannot clear your website or browser cache for you.
Just to clarify: The problem in your case seems to be that you can not find the right image to replace. So the solution should be simple: you just need to find the image in the Media Library. Unfortunately we can not help you in this case ??
Best,
