I am able to confirm the linking issue.
I have turned off all other plugins and turned on AIOE plugin only.
when I go into the post.
1. Type in text.
2. Highlight the text and click the hyperlink button.
3. I noticed that the “Or link to existing content” either won’t open or load anything.
4. I input a URL and press save. It recycles the page, wiping out everything that I’ve typed.
If I turn the AIOE plugin off, it works fine.
We are using the Bueno Woo Theme.
