Hi, unfortunately I' ve an error within the module "Code v3.0.5".
for better visibility, I made screen shots, but here a short explanation:
Insert an code-block, enter the following code snip:
echo '<form><textarea>nothing there</textarea><input type"text" name="name" value="know you find it here" ></form>';
Press save an look at the result.
I found out, that the "keyword" is </textarea> within the "code editor"
But at the frontpage, this breaks at <textarea>
So, something in paring "textarea" wents wrong
This breaks the code-editor after reload the editing page (see attachment containing a picture).
