Self testing – INDEX failed version Version 0.16.0

We tried Operation mode:
1. Varied image response
2. CDN Friendly
and it’s the same

Copying JPEG to index folder (webp-express-test-images/nMaPI3.JPEG). ok
We now have a jpeg stored here:
/bitnami/wordpress/webp-express-test-images/nMaPI3.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”)
Request URL:
The remote request errored
The test FAILED
Why did it fail? It could either be that the redirection rule did not trigger or it could be that the PHP script could not locate a source image corresponding to the destination URL. Currently, this analysis cannot dertermine which was the case and it cannot be helpful if the latter is the case (sorry!). However, if the redirection rules are the problem, here is some info:
Diagnosing redirection problems (presuming it is the redirection to the script that is failing)
Running a special designed capability test to test if rewriting works with .htaccess files
Result: Yes, rewriting works.
It seems something is wrong with the .htaccess rules then. You could try to change “Destination structure” – the rules there are quite different.
It could also be that the server has cached the configuration a while. Some servers does that. In that case, simply give it a few minutes and try again.
Note that if you cannot get redirection to work, you can switch to “CDN friendly” mode and rely on the “Alter HTML” functionality to point to the webp images. If you do a bulk conversion and make sure that “Convert upon upload” is activated, you should be all set. Alter HTML even handles inline css (unless you select “picture tag” syntax). It does however not handle images in external css or which is added dynamically with javascript.

.htaccess files that WebP Express have placed rules in the following files:
- /bitnami/wordpress/wp-content/uploads/.htaccess
- /bitnami/wordpress/wp-content/themes/.htaccess
- /bitnami/wordpress/wp-content/plugins/.htaccess
- /bitnami/wordpress/wp-content/.htaccess
- /bitnami/wordpress/wp-content/webp-express/webp-images/.htaccess
