I have the same problem with a couple of websites. Haven’t found a solution yet.
Yeah, still the same problem. Still ain’t fixed. Any help from the developer is appreciated
I have the same problem!
Is the all ready an idea of the problem / solution ?
I’m on it. I’m guessing it is the security token that expires.

Yes, it seems that the problem was due to the security nonce expiring. It is fixed in the new release (0.16.0).
Hi, I have the same issue on latest version of webp express plugin (0.17.2, previously 0.16.0).
The problem occurs only on larger files (500+ KB):
– admin-ajax.php response is empty for these images
– js throws error “SyntaxError: JSON.parse: unexpected character at line 1 column 2 of the JSON data (bulk-convert.js:248:27)
– bulk converter then stucks and it should be restarted (in the meantime image that caused problem converts to webp)
I tried to change PHP settings but it didn’t help. I also resized all to maximum dimensions of 2048×2048 in order to make them smaller but that solved problem only for some images. Now i’m running out of ideas.
Changing the scope to uploads and themes fixed the issue for me. Thank you so much rosell.dk
