In finishing up a Joomla site this afternoon, we discovered that a number of HTML tags were appearing in uppercase and causing significant validation issues. It was an odd problem because it seemed to be occurring on the PC, but not on the MAC. When we validated the site at W3C, however, W3C was also seeing uppercase HTML tags.

Initially, we thought that some copied content might be the issue. Turns out, however, that disabling 'code cleanup on on startup' and 'code cleanup on save' were the culprit. Once both were enabled, the code reverted back to lowercase without having to re-open individual articles.

More testing to do, but it means that if you have the need to turn off code cleanup, it appears that TinyMCE is not a good choice.
