That’s kind of what I thought, but I’m a relative novice, and I don’t know how to identify the relevant JS to exclude. Could you point me in the right direction?
Many thanks – I did have it working before with self-hosted files. The problem only appeared when I started using S3. I will try your suggestion and report back.
Just spoken with Dreamhost, who are hosting my site. They are certain something with the plugin is causing the 503s. Please let me know if you need any further info.
If you use the X theme, Visual Composer is built in. I think that’s the theme you use? It looks like you have image sizes for the X stacks (Integrity, Renew etc.) built in to the plugin, right?
