Update: I looked at the debug output again at the footer, and I have 26 queries just on that page, and some are reported as errors (red bold text I assume?).

Funny thing, since all of those particular templates or files are not modified...

The only thing unusual that actually gets flagged, has to do with the cronimage function. Just says the following:
