Don’t create some webp files upon request

Plugin redirect to file /wp-content/webp-express/webp-images/doc-root/wp-content/uploads/2016/07/main43-800×367.jpg.webp

This file return error “Error occured while calculating destination path: Image root not found”

File /wp-content/uploads/2016/07/main43-800×367.jpg exist and /wp-content/uploads/2016/07/main43.jpg too

How I fix it?

Live test results:
Testing “WebP Realizer” functionality
UPLOADS
Copying JPEG to uploads folder (webp-express-test-images/wCWUbQ.JPEG). ok
We now have a jpeg stored here:
/home/dev2/domains/………/public_html/wp-content/uploads/webp-express-test-images/wCWUbQ.JPEG
Lets check that browsers supporting webp gets a freshly converted WEBP when a non-existing WEBP is requested, which has a corresponding source
Making a HTTP request for the test image (pretending to be a client that supports webp, by setting the “Accept” header to “image/webp”)
