Applying to sites, please wait... 0 of 1 sites updated

Hi Guys,
When I activate a plugin I get an error.

It switches to this error immediately. It does not time out after a 30 second php setting.
I read some other threads on this issue.
I am in the process of changing the max_execution_ time = 30 to 240 like the other thread said. https://premium.wpmudev.org/forums/topic/applying-to-sites-please-wait-stalls

Is there another setting that may need to be changed?

Thanks for your time
Richard
