Issues with compiled_templates - call to undefined method

Question

We have two web servers in a load-balanced setup. Both servers are sharing a single database. The craft and public folders are rsync-ed between the two so changes on those folders in web1 propagate into web2.

We tried loading a video atom using the following twig:

{% case "video" %}
{{ atom.video(block) }}

It works on our local dev copy and on our staging server at AWS, however on our live site we get this error:

I tried copying the whole runtime folder from AWS over to the live web servers but that did not fix it.

Any ideas on how to get it to work? I would consider myself a novice to Craft so pardon me if there's something obvious that I'm missing.

Thanks in advance.

Update:

Already figured out that it was an error with the upload. Some macros were not properly copied over into live.

Answer 1

It is my bad. Thanks to Brad Bell, I went to check whether the macros were on both the staging and live servers. The macros existed on staging but not on live.

Answer 2

I've had this a couple of times, and have yet to figure out what causes it, but on my server deleting the compiled_templates folder (app/craft/storage/runtime/compiled_templates) fixes it.
