This looks like a conflict you have with another plugin (or your theme) – this happens when your plugin / theme includes JavaScript in an improper manner on every admin page. Can you try temporarily disabling your plugins? If that doesn’t work, try switching to one of the default themes (Twenty Sixteen etc.), makes your changes, then switch back to your original settings.
Hi,
I will do that. However, Picasa, Flickr etc working, except Instagram and SmugSmug. Maybe its browser problem?
Are all tabs rendering correctly for them? From the screenshot it seems like the “Constrain by number of thumbnails” option might be the one getting affected, which isn’t present on the front page of Flickr and Picasa options.
I can tell you for sure if you can give me a screenshot of your JavaScript console – in Chrome if you press Ctrl + Shift + I, then go to the tab at the bottom that says “Console”, you can see the JavaScript errors for that page.
Not all tabs ar working, look.

OK – so, my guess about the script conflict with the slider was correct.
Please temporarily disable your other plugins and retry this. Once your settings are done, you can reactivate the plugins. Specifically, if you have a plugin that deals with a slideshow, that is likely to be the culprit.
Hi,
OK! So there is a conflict with a plugin?
I will sort it out. Keep you informed.

Hi,
It works, finaly. There a some little styling things i need to do again afther reactivating the plugings. Like the text format in the plugin ‘ Quote rotater ‘, its different now. I have to fix that as before.
Seems that is the only issue.
Thanks for your quick help.

Thanks. I am marking this “resolved”.
I have already made changes for the next version that reduce the usage of additional jQuery scripts, so from the next version onwards you shouldn’t see this conflict occurring, unless the conflicting plugin is doing something more than including a script incorrectly!
