I had the exact same issue lastnight, thought it was the SP Tiny too, ended up being SP Avatar.

Based on what I know now, I would bet it’s not actually the SP Avatar that’s causing the problem but rather a conflict with a WP plugin that is not up to date for 3.9. If removing the SP avatar plugin solves your problem and your O.K. with not having it then it might be easier for you to just go with that as the solution.

Both Mr. Papa and I have fully tested all of the SP plugins against an out of the box install of WP 3.9 and Simple Press with all of the optional Simple Press plugins. I believe he tested on Apache and I’ve tested on ISS 7.5. Both of us came to the same conclusion in that without any WP plugins, Simple Press runs as it should.

I am not affiliated with Simple:Press or WordPress in any way so my testing is completely unbiased.

Thank you.

I am still puzzled though as we don’t have an ‘SP Avatar’ plugin! We DO have a class of spAvatar used for CSS styling and an sp_Avatar() display function…

There seem to be quite a few WP plugins coming up in conversations that have not been updated to work with WP 3.9 properly. Sad but there you go.

I thought since I had a couple of minutes I’d check out his problem and realized the same thing. However, in the process and since an avatar is an image I decided to do few more tests evolving around the photo gallery issue.

I’m pretty sure that what we are looking at is a Lightbox issue. I tested a couple of other photo gallery plugins and only the ones that offered Lightbox functionality caused the TinyMCE to fail in my test environment. The new WP photo gallery feature does not offer a Lightbox option which makes me wonder why this popular feature wasn’t included unless there is a known problem with it n 3.9.

I ran the tests again against a fresh build with clean data and the 2012 theme which I don’t think uses Lightbox. The results were the same but I still can’t definitely say it’s the culprit, I’ll watch the net and see if anyone else finds what I may have.

again, thanks for the info!
