Admin Product Listing Issue

Dear Zen Cart Masters,

I recently my Zen Cart sites from one hosting server to another then I got this issue so I believe it is caused by server side configuration.

The issue is that when I set the "Maximum Categories Products Display List" to 39 or above, the admin product listing page does not show or load more than 38 items. It looks like it stops loading the page in the middle of 39th item. It does not load anything below the 39th item i.e. Neither the navigation buttons, the pull down menu nor the footer part is loaded.

Would anybody be able to tell how to fix this issue?

I moved my sites to Bluehost.

My sites's are on Zen Cart version 1.5, 1.3.8a and 1.3.9h all of them have same issue.

Look forward to hearing any advice.

Thank you in advance.

PHP ver 5.3.13
My SQL Server version: 5.1.63-community-log

Thank you for your response.

I just wonder if it is safe to publicly show the admin area of a live site? If it is safe I would install a test site on a subfolder under my domain on bluehost. Wouldn't it be possible for some clever hacker attack my other real site through this test site?

I would appreciate advice. Once confirmed I will post a live link of the test site.
Thank you.

Sorry I misread your problem I thought it was in the catalog display.
and its easier to see the problem and possible solutions in a live site, rather than say a jpg.

NO DON'T post the admin area of your live site.
Sorry I will have defer to others for possible solutions.

Thanks for your response again.

I actually uploaded and installed fresh v1.5 and installed Easy Populate then uploaded test products.

I changed the Maximum Categories Products Display List to 100.
Strangely, it works fine. The admin area product listing shows all items and all footer items including navigation with no problem.

With all 4 other real sites have same issues although they are all different version of ZC and have different add-on modules.

Fresh install does not have issues but existing ones do, which means most likely one or more of add-on's are causing the issue, right?

I cannot think of any common add-on that relates to admin area....

Does this info help?
