Instructions for installing the module with the OpenCart modification

Before performing any actions to install the add-on, we strongly recommend that you create a backup copy of your site files and database;
Download the add-on file for the OpenCart version you need from our website;
Go to the "Installing extensions" section and click the "Download" button;
Select the downloaded file and wait until the text "Settings successfully changed!" appears;
Then go to "Add-ons Manager/Modifiers" and click the "Update" button;
Now you need to grant permission to view and manage the add-on in the "System -> Users -> User Groups" section by clicking "Select All" and saving the settings.

After these steps, the module will be installed and you can start using it!

In the site's admin panel, go to System -> Tools -> Error Log. The log will show current site errors. If there are no errors, enable error logging in System -> Settings -> Server -> Log Errors -> Yes.
If you have FTP access, open the logs/error.log file on the server. The latest entries will show the cause of the error.
If errors are not displayed, enable them via.htaccess by adding the code below:

php_value display_errors 1
php_value display_startup_errors 1
php_value error_reporting E_ALL

The add-on file name must end in.ocmod
The add-on archive must have the.zip extension.
The archive may contain files install.xml install.php install.sql and an upload folder (may be empty if it is a modifier).

This error means the upload folder is missing from the installation archive. Such folders should be inside the module.ocmod.zip file and may be empty, but are required in OpenCart 2.

Before installing the module, you must remove the previous version of this modifier.

Perhaps such a module requires manual display on the website. To do this, go to Design -> Layouts and display the module in the desired layout in the desired location.
If the display of the add-on's content is implemented using a modifier, there may be an incompatibility with the template. The modifier will need to be adapted.
In OpenCart 3, after installing an add-on with a modifier, you need to update the template engine cache (the button with the "gear" on the main admin page in the upper right corner).

The module files are not uploaded to the server. Check their availability using an FTP client.
The store administrator has not been granted permission to view and manage the module in the "User Groups" section.
Some modules make changes to website files as modifications, creating a cache of modified files rather than changing them. After installing such modules, you must update the website's modifier cache.
In OpenCart 3, after installing an add-on with modifiers, you need to update the template engine cache (the button with the "gear" on the main admin page in the upper right corner).

In this version of OpenCart, there's an error on line 21 in the system/modification.xml file that prevents other modifiers from being applied. Replace this line with the following and update the modifier cache:
```
 <![CDATA[$loader = new \Twig\Loader\ArrayLoader(array($filename. '.twig' => $code));]]>
```
