CMS Made Simple Forums

Hi
I get a random error on my site 7dias.com.do. Sometimes any page on the site doesn't load completely. I have my javascripts at the bottom of the code and the footer together with the javascripts don't load resulting in missing functionality in my site (facebook comments, slider javascripts don't load).
I clear the CMS cache and everything goes back to normal. I have tried using {nocache} for different elements on my templates, we have disable smarty cache on site admin > global settings > advanced set up and none of that seem to work. We can't replicate the problem either.
We are running CMSMS 1.11.3
Any one out there with any suggestions?

Check third party modules and tags for compatibility with CMSMS 1.11+
Php error log or debug mode can give hints...

Thanks for the help. The problem just resurface a couple of minutes ago.
We had a global content block with the footer code in it. We skip this GCB and instead loaded the code directly onto the template. This seems to have worked things out. We created a new GCB in CMSMS for the footer and are using it again. So far so good. It worked and we didn't have to clear the CMS cache. The previous GCB was edited with Template Externalizer and we suspect this could be the culprit.
We are monitoring to see if we get the problem again.
