I'm using an e-commerce theme from Sarah Neuber, who disappeared and wont offer support anymore. I'm going to switch to a dedicated e-commerce platform (Bigcommerce perhaps?) but until I do, I'd like to get the current theme running a little better. I know it's a long shot without a specific error and the offending code, but here it goes. In Dashboard > Store Administration > Manage Orders, when there are many orders, the page stops loading prematurely. This is a problem because at the very bottom is the dropdown menu that's needed to process orders that are checked (for example, to send them from "New" to "In Process").
A while ago it gave a Fatal Error at the bottom: "Maximum execution time of 30 seconds exceeded in ... on line ..." However, the location of the error seemed to be random as sometimes it was listed as cache.php, cart_actions.php, or post.php.
In php.ini I changed the max_execution_time from 30 to 600. I no longer get the Fatal Error but I think that may just be due to a WordPress update because I changed the execution time back to 30 and the error didn't show up.
The page loads very slowly for several minutes, then just stops. Do you have any idea how to make it load completely? I don't know much coding so any help is appreciated!
