I’m not the author, but I’m running WordPress 5.6 and this plugin works well for me. Maybe try installing on a blank WordPress install and see if it works for you. If so, that would indicate it is a conflict with your theme or another plugin.
@ahmis sorry for the long delay. Yes an update is in the pipeline.
Although, as @jodamo5 stated, the current plugin should be working in WP 5.3. Do you have checked if any other plugin causes the error by disabling all plugins for a short time?
What theme do you use?
Any chance the next update will support Beaver Builder? I use it on several Beaver sites, but I can’t seem to get this plugin to update the image in /uploads/bb-plugin/cache.
Thanks

sorry, no plans to support Beaver Builder.
