Categories/Products Page not loading in admin

Hello All,

This is a new problem that is stumping me. I have three stores, all V1.5.1. Just this evening, I went to add a new product to the store and after clicking Catalog and then Categories/Products, the page just loads the header and all the info down to the Categories/Product Display Order: drop down.

After that, there is nothing. I checked my other two stores, and they operate normally. I checked the website, and the product appears fine in the store and I can add it to the cart, but in admin, I have nothing.

I have cleared my cookies, restarted my browser, restarted my computer and also used a different browser with the exact same results. This is the only page that seems to be affected, but I have no clue where to begin in fixing this issue. Have any of you ever seen this problem and is it an easy fix? The store has been up for over a year. I don't understand why it's doing this to me now.

Thanks,
Tony

Do you have any debug logs in your directory /logs happening when you go to the page in the Admin?

The error message states: error at category_product_listing.php on line 291. When I open it up, it ends at 291. When I open that file from my other stores, it continues on to almost 450 lines. Somehow the file got corrupted and truncated. Should I just copy and paste the missing code from the other store into this file?

Never mind. Copied and pasted and tried it. It works fine now. Thanks for the help.

Tony
