Hi, our site always encounter this problem which the backend or wesbite is not working properly.Please check screenshot below. Please advise. This happened very frequently after we switched to this theme.
Please contact your host support. Our theme does not influence this. Also, try to clean your content from demo which you do not use. Your screens show that you have exceeded the limits provided by your host.
Next, delete all the demo content, it contains a lot of elements which you may not need. Disable all the third parties plugins not related to the theme.
