I’m experiencing an identical problem. Did you ever find a solution? WordPress 3.2.1
Worth noting that this issue continues even with all plugins deactivated.
EDIT:
On further inspection I realise that if I select alignment none for the image everything works as it should be any of ‘left’, ‘center’ or ‘right’ prevent the link url from being updated.
Can you reproduce this on the default TwentyEleven theme?
I can reproduce on TwentyEleven. I’m also able to reproduce across other themes and child themes, with or without plugins activated, across 2 different Hosts.
I can get the link to store correctly IF :
1. I allow WP to keep the default link URL to the full image post, then after inserting it into the post, edit the link retroactively.
2. I edit the default link URL _BEFORE_ inserting it into the post.
3. Choose “None” for alignment and remove the link – then I’m able to retroactively update the link on the image.
If I choose an image alignment AND remove the link URL, I’m unable to retroactively add a link to the image via the WYSIWYG editor. (I can manually add a link to the image by switching to the HTML tab and hand-coding it.) What happens is the image editor fades out like expected, but the link does not save. If I use the “link” button, when I try to save the link by clicking “Insert”, the screen jumps up, the link disappears from the form field, and the bottom of the edit box gets a long white horizontal rectangle at the bottom. I have to cancel out of it, and the link does not store.
If I activate TinyMCE advanced on a TwentyEleven child theme and use the “link” button to add a link retroactively (after choosing an alignment, removing the default link url and inserting into the post), I’m getting this error :
FORBIDDEN
You don’t have permission to access /blog/wp-content/plugins/tinymce-advanced/mce/advlink/link.htm on this server.
Additionally, a 404 Not Found error was encountered while trying to use an ErrorDocument to handle the request.
To us, it appears something is happening in TinyMCE between the image alignments Left, Center and Right and when you DO NOT specify a link url in the same upload/insert screen that makes the link/edit buttons unable to retroactively add a link to an image via the WYSIWYG editor.
Yes I can reproduce this on the default 2011 theme (note this is strictly an issue with the admin interface, so I wouldn’t think the theme would affect it anyway). No I never found a solution for this. I have been using workarounds like those described above.
i can reproduce this as well on the default 2011 theme and wp 3.2.1 and the latest trunk version
Appears to have been fixed on the upcoming 3.4 version.
