Quantity 1 in cart Opencart 3
Want to sell digital goods on Opencart 3.0 - then you need the Quantity "1" module in the cart. After applying this module, the customer will be able to add products to the basket only in the amount of 1. Even if the buyer adds one product to the basket several times, the basket will still contain the amount of this product 1. Also, the buyer will not be able to change the number of goods on the basket page, placing an order - it will always be equal to one.
Selling products in one copy is suitable for information products since it makes no sense to sell one file to a client in the amount of 2 or more. Selling goods in only one piece can be useful in other cases - for example, if you sell very rare goods, such as antiques, and coins. Or you want to sell one copy of the product in one hand.
When changing the number of goods in the cart or on the checkout page, the module will not allow to increase it by more than 1.

Solution:
Download and install the Localcopy OCMOD add-on
After installing this add-on, you need to go to the Modifiers section and click the "Update modifiers" button. After that, you can install other modules
There are some problems and possible solutions:
1. The template cache has not been reset - you need to update the cache [screenshot]
2. When you previously edited template files through the admin panel in the "Theme Editor" section, they were saved in the database and it is no longer affected by ocmod modifiers, this is an Opencart 3 issue. You need to install an extension [download] and update the modifications in the admin panel.
3. Your template is based on TPL files (*.tpl), while in Opencart 3 templates should be in TWIG format (*.twig). The problem is that ocmod modifiers do not affect TPL files - all changes must be made to these files manually.
You need to enable the output of all php errors on the screen - for this, in the .htaccess file at the end you need to add the lines:
php_value display_errors 1
php_value display_startup_errors 1
php_value error_reporting E_ALL
Now, instead of error 500, an error code should be displayed, which will indicate the issue.
There is a bug in official Opencart 3.0.3.5 - 3.0.3.6 patches - modifiers do not work with twig files due to an error in the standard modifier /system/modification.xml - the second operation from this modifier does not work.
The problem occured in official github and proposed solution is https://github.com/opencart/opencart/blob/3.0.x.x_Maintenance/upload/system/modification.xml
We made a fix modifier according to these recommendations, it will replace the /system/modification.xml file with the correct one.
Solution:
1. Back up your /system/modification.xml file
2. Download the fix modifier from the link and install it in your admin panel
3. Update mod cache
4. Update twig template cache
