working on fixing that, so we will get back to you if needed 🙂 * Best, * Plugin Author [Pedro](https://wordpress.org/support/users/petredobrescu/) * (@petredobrescu) * [3 years ago](https://wordpress.org/support/topic/uncaught-typeerror-72/#post-16749608) * Hello [@monoloid](https://wordpress.org/support/users/monoloid/), * After checking the error and the details you provided, it looks like you have in the optimizing queue some very old items/images (probably left there somehow from 2022, or you used an older version of the plugin until recently). We have changed the way the requests are done to the optimization API and this is why you get that fatal error. We’ll include a fix for this error in the upcoming version 5.2.3. * Meanwhile, the quick solution for this issue is this: - Clear the existing queue by going to Settings -> ShortPixel -> Tools tab - > Clear the Queue - Start the Bulk Processing again from Media Library -> Bulk ShortPixel * After the queue is cleared this error should no longer show up. * I would appreciate if you could confirm that the above solution works in your case!
