Close Store Manually?

V 4.2.4 I was adding products and hit the clear cache and then the site went haywire.

Is there somewhere in a file to toggle the store off since I don't have an admin panel that works?

I don't know what happened. Store was working fine. I have another v4.2.4 store on same server that is fine so I'm not sure what has happened.

Just create an index.html file in the root directory of your CS-Cart installation with the content from the store_closed.html file. Then open this file in the file editor and change [title], [banner] and [message] placeholders to the required text (e.g. Store temporary closed, e.t.c.).
