Frontend And Layout Page Suddenly Slowed To A Crawl

Hi guys,

I have an issue with my Cs-cart website whereby the frontend and the layout page setting suddenly became so slow.

I've tried to clear cache, clear thumbnails, delete cache folder to no avail.

Other pages inside the admin panel works fine though. Any help is greatly appreciated.

My cs-cart version is 4.2.4

If you have any 3rd party modules, please disable them and check the result at first
