I have some plugins installed in my website and some of the plugins I can use to embed certain type of data in post by clicking on the plugin button in TinyMCE editor. When I click on the plugin button in tinyMCE editor a popup windows opens (it should open and it always did before) but instead of opening the plugin's configurable options it shows me the 404 Error page. This is happening for every button in TinyMCE editor which opens an inner window/dialog box/popup.I even tried resetting the permalinks to default but that did not help. I also switched off all the plugins and tested them one by one but that did not work either.
Here is the error snapshot https://docs.google.com/file/d/0B2xvqq9TGjQpbGhLMFV0cGJ6SVk/edit
A few plugins i m using :
WordPress Post Tabs
How do I fix it?
