Suddenly getting blank pages when trying to edit products.

Here's what the log file says:

PHP Fatal error: Call to undefined method object Info::updateObject Info() in /home/content/43/4941343/html/com-m/wax_candles/includes/modules/product/collect_info.php on line 65

BTW - there does not seem to be an issue with line 65 of /home/content/43/4941343/html/com-m/wax_candles/includes/modules/product/collect_info.php

it was working... it stopped.... line 65 is perfect. its beautiful... its just a perfect line...

you are running zc v1.5.4.

see:

https://docs.zen-cart.com/user/first..._requirements/

looks like your host upgraded you to php 7.x.

best.

I wish it was that easy. Then maybe I could downgrade my php version in the server. However, this particular server will not run higher than php ver 5.6.

what does admin -> tools -> server/version info say?

look for the php version there as in:

https://docs.zen-cart.com/user/admin...s/server_info/

i don't trust your cpanel.... maybe it is right.... but lets find out for sure.

looks good there too...

PHP Version: 5.6.27 (Zend: 2.6.0) PHP Memory Limit: 64M	PHP Safe Mode: Off
PHP File Uploads: On Max Size: 32M

So two questions:
Line 65 of admin/includes/modules/product/collect_info.php, does it look like this?:

$pInfo->objectInfo($product->fields);

And if you open admin/includes/classes/object_info.php what are the contents? Is there a method called objectInfo? This would be code within the class definition identified with function starting the line. The existing 1.5.4 function is on line 26 and reads as:

    function objectInfo($object_array) {

It could be possible that someone was attempting to make this php 7.x ready and didn't realize that there were direct calls to that method and therefore changed its format.

Please identify discrepancies to the above as related to the existing store.

They are as you describe.

Hi there.

I am having a similar problem. When I try to add a product, my admin are gives be a blank page. - As, I am still in admin but it gives me no option to add anything. - Blank page.

Blank pages are typically a result of fatal PHP script error, meaning something's gone wrong and it can't finish drawing the page.
The cause is recorded in logs on the server.
https://docs.zen-cart.com/user/troub...ng/blank_page/

Find out the error message in the logs, and take action to fix the error accordingly.

Typical cause is using an old Zen Cart version on a server that's got "too new" a PHP version on it.
