Hi,

Drupal newcomer here.

I've using a custom theme, and occasionally get a huge list of warnings that display either on page or when I try to edit the page. These errors appears after I've done something that is presumably wrong. In this case, I merely disabled the 'menu block module'. The warnings don't really give me an indication of what I did or what's causing them, and they always look like this when it occurs:

I've tried asking the theme's forum support for help, but there's a continuous communication problem that makes problem solving extremely difficult.

thanks!

first thing you do is test on a core theme to verify that the issue is theme related. If not copy and paste meat of error into google and read through the many discussions around the error.

Sounds good. Still occurs in core theme (Bartik). So I will get very Googley now. Thanks!

In this case, it won't help. The messages all show up when code is rendered, and the problem happens somewhere further upstream. Some module is adding some bad render code. The only way to figure out which one is to disable modules one at a time until the problem goes away, indicating which module to inspect for the problems.

Ok, that sounds right. My spidey senses were telling me module-related. Will try them one at a time. Thanks!

The theme developers told me to downgrade from field collection module from 7.x-1.0-beta11 to 7.x-1.0-beta8. They didn't say why (they aren't exactly masters of communication).
