Thanks Mauno
Luckily I have a quiet few days, so am able to do a bit of testing and playing around:
At the test site http://test.wittenborg-online.com I used a clean cvs download, changed the theme to cornflower, removed all blocks from the front page, as well as news items and “topic”, resulting in only 1 error on validator.w3.org .. and still the html editor shows the fault editor_78e731027d8fd50ed642340b7c9a63b3.generate(); //]]> - allowing only html edit.
I also installed a new, downloaded cvs 1.8 version, and loaded it with one of the Wittenborg themes – and html editor still worked – so it isn’t the adapted theme.
By the way, at least ½ the html errors were down to pasted code from Front Page (staff publishing news, etc) and the rest were from the theme itself!
Careful conclusion (?) - I think it’s an upgrade problem, and I think it’s related to the database.
What I need to find out, is whether it is a result of our particular installation – upgraded many times in the past years, moved from Postgres to MySQL a of year ago, etc – or if it is a general upgrade problem from 1.7.1 to 1.8.
I’m afraid I am not a php or mysql programmer – I understand a lot and (at the moment) use moodle to facilitate our small institute, but as a business school director don’t have enough time to sort this out (my excuses for not offering a solution).
If it is a problem of our particular installation then I shall hire someone in to fix it (and post the solution for anyone who may have the same problem), however if it’s a general upgrade problem that will be fixed moodle wise, then I’m a happy man!
