Cannot add products to a new order entered in the Admin Dashboard [ SOLVED ]

Running OC Version 3.0.3.3

This is a new, clean install. I am unable to add any products to a new order that is being entered in the Admin Dashboard area. Placing orders on the front end works fine. I have tried clearing the cache in OC and the browser. Have tried three different browsers. When I choose a product and click Add Product, nothing happens. and I can't continue with placing the order. There are no reported errors in the error log. Any suggestions would be appreciated.

monitor your web developer tools console while doing that.

I'd suggest this too, especially the JS Console and Network tab.

That worked. No clue why. It seems strange that just having that console open allows me to enter products. I didn't see any error messages in the console. I am assuming it is some kind of bug in this version of OC? I am not having any issues with 3.0.3.1

Thanks to both of you for the tips.

Hmm, I am not sure this can be claimed as solved, as i have not actually seen an answer that resolves it. I have been using the front end for entering orders, but recently decided to use the admin version for a basic type of order. I have the exact same code for my localhost on my laptop and the one that is published. Testing it on the localhost worked fine, as expected, no messages, select product, saves it properly, etc. Trying exactly the same in the live environment means that i can't add a product to the order - I add the order details, go to the product tab, try to add a product and it spins but does not return the product, no message, no error, tried console open, network tab open - nothing. It just does not add the product.
I tried searching various threads o this topic, but they all seem to just die... I am using OC 3.0.20, for a few years now, also journal 3, very stable, no issues.
Anyone discovered an actual fix?
