I’m using WP v4.1 and theme is Twenty Twelve (Child).
I upload my media to the library:
1. Click on +New
2. Click on Media
3. Drag and drop the file into the Drop Area
4. Once uploaded I click on Edit next to the uploaded file
5. Copy the File URL
I then create a new post or open an existing page, type out my text, highlight the text i want to link my file to, click on the paperclip, past the File URL in the URL box and click on the Add Link button.
I then choose my Format and Categories and then Publish.
I have only happened in the last couple of days, sinceI have had to un publish my stream page which is connected to my BuddyPress – Could this have anything to do with it. However, I have re published the page and repaired the BP Links but the problem is still there.
