Unable to save changes made to "widgets"

It usually happens because of problem with your browser, try clearing cache. If it wouldn’t work try to do it with another browser

Try clearing any caching plugins on your site as well.

Neither one of those things helped. Also I can close “safari”, and go to a windows computer, then open wordpress and that “gray circle” is still spinning.

Try deactivating your plugins to see if any are causing that.

This may be the theme problem too, try changing it

and that “gray circle” is still spinning.

you can try bumping up the memory alloted to wordpres to see if that is the issue.

Thanks for all the help. I deactivated the “plugins” and that clear the problem. I couldn’t have done it without this forum.

Thank you
