Can’t bulk convert image

Hm… The javascript makes a request to get list of unconverted files. It should be a JSON formatted object, however, for some reason, it is not.

I wonder what it is, then!

Can you help me out with a little debugging?

1: Open file: plugins/webp-express/lib/options/js/0.16.0/bulk-convert.js
2: In line 11-12, you should se this code:

    jQuery.post(ajaxurl, data, function(response) {
        if ((typeof response == 'object') && (response['success'] == false)) {

Between those two lines, insert this code:

        var responseObj;
        try {
            responseObj = JSON.parse(response);
        } catch (e) {
            html = '<h1>Error</h1>';
            html += '<p>The ajax call did not return valid JSON, as expected.</p>';
            html += '<p>Check the javascript console to see what was returned.</p>';
            console.log('The ajax call did not return valid JSON, as expected');
            console.log('Here is what was received:');
            console.log(response);
            document.getElementById('bulkconvertcontent').innerHTML = html;
            return;
        }

Next, reload the WebP Express settings page and click “Bulk Convert”. I expect that you now see an error message, which directs you to look at the console output.

Please copy the console output and paste it here, thanks!

It is probably still on the cached version.
in plugins/webp-express/lib/options/enqueue_scripts.php, line 7, you can change this line:

$ver = '6'; 

to:

$ver = '7'; 

This should force it to use the changed file

Have you tried hitting F5 / ctrl+F5 to force refresh? https://refreshyourcache.com/en/cache/

Try to open the “Network” tab in DevTools (two tabs to the right of “Console”). You should see a request to “admin_ajax.php”, probably several. To get the right one, clear the console (the red button) and then click “Bulk Convert”. Doing so should produce a request to “admin_ajax.php”. Then click the on “admin_ajax.php” and select the “Response” tab. Is it empty too?

Oh, yeah, that would be the easiest way for me to find the error. Thanks 🙂 My email is [email protected]

I got the login, thanks

Found it. Finally!

The problem was special characters in some of the files. I have fixed it on your installation. It now gets the list. It still fails the individual files which have special characters (including the two first files)
