Intermittent site loading Problem

[buildingblocks]

Zen Cart 1.3.8a - has all the updates
originally hosted on a hostgator account
new hosting is on a hostgator reseller account


I moved a zencart from one host to another. This cart was working nicely on the first server.

To make the move I followed the directions as outlined here

https://www.zen-cart.com/tutorials/i...hp?article=100

I have a number of mods including multi-site installed. There was a little issue getting the multi-site working again only because the new site was setup just a little differently then the original site.
I got the multi-site working.

The problem is this.

The site is going down intermittently. It works for awhile and then it stops loading and the domain name loads a
'holding page' of some sort. I don't know what to call the page but it has the domain name of my site with a bunch of 'related searches' links on it. Nothing to do with the zencart.

This happens to the front-end of the cart as well as the admin. When the site goes down the admin won't load either. That holding page comes up.

A little while later I'll check and the site is back. I did some minor work in some of the language files and the site loaded fine after each change.

If I made an error in editing an includes file any problem would have shown immediately. Would an editing error result in intermittent loading problems for the front-end as well as the admin?

Anytime an error has occurred it's obvious the zencart is there but it's is having a problem loading.

What's happening is as if there's nothing on the site but that holding page.

I'm told there is a scripting error with the cart. If that is the case what do I look for? How is a scripting error for zen cart corrected?

Thanks anyone

Would really appreciate some feedback.
