Hi, in regards to your question.
And are you using all AIOWPS features? No.
I don’t think enabling all features is a great idea. The reason being is because different sites have different plugins and or theme and the server might have different configurations that might clash with some of the plugins settings. However in saying this some people have enabled almost all the options in the plugin without a problem.
I am running version 4.3.2, which is the latest version with some bug fixes and improvements. The score in my dashboard is 280/505.
I have replied to your message sent via my contact form. You can submit your backup settings. I will look at them. However I am sure that the issue you are experiencing is related to a plugin conflict or server setting.
The developers and I have checked Yoast plugin with our plugin and many users are also running both plugins without any issues.
Kind regards
