I am having a similar issue.

When editing a post the text in the visual editor is often white (so invisible unless selected).

Then after switching between visual and HTML, the visual just shows HTML.

– Visual editor is enabled
– Still persists with all plugins disabled
– Still persists with the wordpress default theme.

I had a look into this. In normal circumstances I think wordpress does it automatically. You should be able to find this code in the formatting.php file or another file (can’t remember which).

$text = str_replace(']]>', ']]>', $text);
$text = strip_tags($text, $allowed_tags);

However, a plugin may interfere, such as a plugin for advanced excerpts or any plugin involved in creating an excerpt.

Therefore make sure that code is in there. So you may want to study the plugin’s code and add that code to it. I added the following and it got rid of most unwanted code in excerpts:

$text = str_replace(']]>', ']]>', $text);
$text = preg_replace('@.*?</script>@si', '', $text); //remove javascript
$text = preg_replace('@<![\s\S]*?--[ \t\n\r]*>@', '', $text); // remove CDATA
$text = strip_tags($text, $allowed_tags);
$text = preg_replace('<code>\[[^\]]*\]</code>','',$text); //remove anything in square brackets

Seems to be working again now

I asked my host about the problem, they looked into it and concluded:

Your image is being passed for processing to a php script at smushit.com. It is that script that is returning “could not create temp dir” and failing. Therefore, there isn’t anything you can do site/server wise to fix this issue. You will have to contact smush.it to get them to fix their script so that it can smush your images.
