[Plugin: WP Photo Album Plus] Slide show not working anymore

I currently did the following changes:
* just upgraded to 5.0.7 (but not sure if this chaned anything)
* simplified settings by removing social media etc …

Current status:
When logged in it still does not work
But if I am logged out it works fine

Any ideas ?

I did a clear and reset of all my browser info.
When going to my site first time it works well.
The only isue remaining: once I log in, I can start the slide show and the page is somehow scrambled.

In those case, just below the place where the photo should come I have now:
