Magento – how to upload video file through wysiwyg editor in magento

So after a day of diving into this issue; disabling modules, enabling modules, removing changes in local etc etc, I found the problem.

I used an extension called PhPro_Translate to do a large amount of translations for front and backend from English to Swedish and so in my std install I have just inserted all the rows of translations into core_translate (as the extension does). It turns out that one of the 80 or so translated strings under the Mage_Cms module cause the error. I honestly did not have the energy to look into exactly which string as I still have 3400 rows working :), but I have a vague idea it could have been a Swedish word with umlauts.

In the very unlikely event that someone else runs into the same problem, that's the answer!

Cheerio

UPDATE: Since this could have implications in other contexts, here's what caused the js error. In one of the translations I had used single quotes around a word to denote it was the original English term but I had forgotten to escape the quotes. Voilà!

In order to allow to upload and link pdf file, I modified your config.xml

<?xml version="1.0" encoding="UTF-8"?>
<config>
  <modules>
    <Pdf_WysiwygFiles>
      <version>1.0.0</version>
    </Pdf_WysiwygFiles>
  </modules>
  <adminhtml>
    <cms>
      <browser>
        <extensions>
          <allowed>
            <pdf>1</pdf>
          </allowed>
        </extensions>
      </browser>
    </cms>
  </adminhtml>
</config>

For the icon you can use css styles. Add this in your stylesheet, for example: skin/frontend/rwd/default/css/styles.css

.col-main a[href$=".pdf"]:after {
  content: "";
  display: inline-block;
  width: 20px;
  height: 20px;
  background: url(../images/icon_pdf.png) no-repeat;
  margin-left: 5px;
}

EDIT:

Removed this part:

          <media_allowed>
            <pdf>1</pdf>
          </media_allowed>
