Carley – I know we have had a few people with this issue but usually it does come down to the jQuery conflict issue and the problem is that if there IS such a conflict even if not responsible for the editor problem, it DOES have to be sorted out first so we can then look at other possible culprits.
If possible – and I realise it isn’t always so easy – a quick test is to switch your site briefly to use the WP default theme to ascertain if the problem still exists – and then switch right on back again of course.
But your theme IS doing thinghs incorrectly. This codex article explains this in detail – http://codex.simple-press.com/codex/faq/troubleshooting/what-is-this-jquery-conflict/ (note you will need to currently log in separately to the codex).
In your case it is complicated by the fact that the theme is loading a ‘custom’ version of the jQuery UI library and we do not know what that contains. But can find out of the loading is corrected as we can then see what might be missing and add it back in.
So – the culprits in the theme are:
- jquery-ui-1.8.16.custom.min.js
- jquery.ui.core.js
- jquery.ui.datepicker.js
- jquery.ui.widget.js
all of which are being supplied and loaded from the theme instead of using the WP supplied versions.
You can talk to the theme author and suggest they change things to ‘enqueue’ these scripts properly from the WP library or – if you can find where they are being loaded, we can help you correct the code which is usually not that hard to do.
