Test failed (no permission)

Hi,
I used your plugin in almost 5 website and all works great!

Today I had an issue with a new website, I’m unable to convert images.

I asked to host support and they said “ask to developer first” 🙁

This is what happens:

Result: Failure
Message: None of the cwebp files located can be executed. All failed with return code 126 (permission denied)
Conversion log:
Converter set to: cwebp

*WebP Convert 2.1.4* ignited.

The following options have not been explicitly set, so using the following defaults:
– alpha-quality: 85
– auto-filter: false
– preset: “none”
– size-in-percentage: null (not set)
– skip: false
– rel-path-to-precompiled-binaries: *****

Encoding is set to auto – converting to both lossless and lossy and selecting the smallest file

Converting to lossy

We in fact have 3

**Error: ** **None of the cwebp files located can be executed. All failed with return code 126 (permission denied)**

What can I ask to host support to check?

Thank you
