WordPress endless loading both frontend and backend

Hi guys,

I am in need of help, desperately!

My WordPress site is getting stuck when trying to load the site, that goes for both frontend and backend.
Sometimes I can use the site for 10 minutes before it starts the endless loading, and other times I can’t access the site at all. The loading doesn’t time out, it just keeps loading.

I’ve tried disabling all plugins to see if this was an issue, but didn’t help.
I have removed the Google Analytics code from my footer, didn’t help.
I have updated my permalinks setting creating a new .htaccess fil, didn’t help.

I am just out of options at this time, and want to know if anyone might see what I can’t.

Hope to hear from you!
