We have several customs fields which use the main wordpress editor. (see screenshot)
If we upload an image in visual mode, then save the post the image we have uploaded is not visible - it hasnt saved. (But is in the media library)
If we upload an image via text mode it saves fine
This would suggest an issue with the editor
I have tested with a blog post and the default editor (with any additional custom fields) and everything works fine
I re installed wp several times, uninstalled and reinstalled plugins but the problem still persists
I cant say for certainty when this started (perhaps 6 weeks) but it wasnt always like this
perhaps I should try an older version of the toolset plugins?
