Writing extensions for Opencart 2.3.0.2

Hi, I have just started new project using Opencart 2.3.0.2 (latest avaialable version).

But when I tried to use extension my own extension or third party and save settings a I got an error This problem has been already discussed here viewtopic.php?t=169033, but this is just compatibility fix that will work with VQMod.

I have tried to find any guidelines, changelog or anything that can help to find out correct way of writing extensions for OpenCart 2.3.0.2, but unfortunately nothing.

Could someone provide any guidelines or changes to be done in existing extension to make it work.

P.S. If you check all permissions in User Groups (including installed extension) it will throw an error but save settings of this extension.

The same error I have found that extensions should change POST part for example
It is
But should be

I've changed this line, and it really works, but redirects to the main extension page.

I am so disappointed, such a great community, but no information for developers how to write valid code for new version of OpenCart and weird solutions and one paid plugin.

Please add guidelines or any other information that helps to migrate and modify existing extensions.

1. if you want to redirect to another page, then change that code to whatever you like: 2. if you are developer, then you should be able to read the existing code and use that as base

Well, a Developer, familiar with the OpenCart MVC(L) Framework, VqMod and OcMod, should not have a Problem, to find out the differences between OC v.2.3.x and older OC Versions. A simple File Synchronizer like winMerge could be used, to easy find different Files/Content, and File Locations, in two Versions of OC, troughout the entire Software.

In addition, the Web is full of informations, it may just take some time, to find it all. It's like in real Life, hard work, at least, if one plan's, to someday know, work and act like a Dev!

But when it comes to paid Extensions, no-one else but the Mod-Creator, would, legally, be able to assist on such anyway, just to mention this!
Good Luck
