An issue like this is usually caused by a javascript error since the list mode doesn’t use javascript. On your site I’m seeing the following error:

Uncaught TypeError: Cannot read property 'srcsetAttr' of undefined
    at siteground-optimizer-lazy-load-images-responsive-js.min.js:1
    at siteground-optimizer-lazy-load-images-responsive-js.min.js:11

siteground-optimizer-lazy-load-images-responsive-js.min.js:1

There are also 4 more “resource not found” errors, but I don’t think those would cause this issue (though, you still may want to look into and resolve them):

Failed to load resource: the server responded with a status of 404 ()
bootstrap.min.css:1

Failed to load resource: the server responded with a status of 404 ()
bootstrap-glyphicons.css:1

Failed to load resource: the server responded with a status of 404 ()
collapse.js:1

Failed to load resource: the server responded with a status of 404 ()
skip-link-focus-fix.js:1

I’m guessing these errors existed before. But, when a plugin updates, the order that all your plugins load may be modified. Previously, the ticker scripts may have been loading before the siteground-optimizer script threw an error. Now, it’s most likely loading afterwards and being affected by the error.

You can try using a plugin like https://wordpress.org/plugins/plugins-load-order/ to force the ticker to load first, which may resolve the issue. Otherwise, the javascript error will need to be resolved to get the scrolling ticker back up and running.

@colinriche thanks for letting me know. I have released another update that resolves this error.

@pape8291 Thanks. I have this resolved now in 2.2.7… Hopefully that’s the last of bugs!
