Random 404 error.

Hi,

I was experimenting a strange random 404 error. Everything seemed to work perfectly but suddenly it failed to load some pages redirecting to 404 error page.

Sometimes, when this happened on a page, it ended up happening on almost every page.

But recently I was experimenting this issue particularly on wordpress child pages.

It seemed to work when I tried to load parent pages.

Finally I deactivate the Plugin Organizer and I’ve spent more than a week without having any 404 error.

Maybe it’s a conflict with another plugin, maybe Siteground Cache Plugin – SG Optimizer

Any help on this issue would be appreciated because now the web load time has increased considerably.

Thank you in advance.
