You can download the archive with an extension from your personal account on this site. After successful payment go to 'Account -> Downloads' choose and download extension version for your OpenCart store version.
If you just installed a new OpenCart module and you’re getting Permission Denied error, it means that your User Group does not have rights to view or edit the module. What you need to do is go to 'Admin Menu -> System -> Users -> User Groups' page, select your user group from the list and hit Edit button. Then select your module both in Access Permission box and in Modify Permission box. Click Save button.
VQMod is a simple modification system that lets developers make changes in OpenCart core files (system files) without actually editing them.
For example, if you want to change “Contact Us” page in your default OpenCart theme, you don’t need to edit theme file itself – you can create (or download) vqmod extension file that will change the page without modifying the actual theme file. It’s all done by search/replace technique – vQmod makes changes while loading your OpenCart store.
What is the benefit of using vQmod instead of directly editing core files? Since there are no OpenCart core modifications, it’s much easier to update OpenCart system and themes, and add new functions to the existing store.
The File Transfer Protocol (FTP) is a standard network protocol used for the transfer of computer files between a client and server on a computer network.
Using FTP, a client can upload, download, delete, rename, move and copy files on a server. A user typically needs to log on to the FTP server, although some servers make some or all of their content available without login, also known as anonymous FTP.
Please go to administrator menu "System > Settings > Default Store > Edit > FTP tab" and check your FTP credentials. Most likely you entered the wrong login or password. More info >
You need to go to administrator menu "Extensions -> Modifications" and remove an old modification record (file). More info >
Please go to administrator menu "System > Settings > Default Store > Edit > FTP tab" and check your FTP credentials. Most likely you entered the wrong FTP Host. More info >
You need to check the FTP Root option in your FTP credentials (go to administrator menu "System > Settings > Default Store > Edit > FTP tab") . If this option is incorrect the extension was installed to the wrong directory. More info >
You need to try to re-install the extension. Go to admin 'Extensions > Modules' find the extension and click Uninstall button then install it again (click Install button). If it doesn't solve the problem, most likely your database user doesn't have permission to create a new table in the database. You can create the extension table manually from '.sql' file in the '.zip' archive with the extension or get permission to create a table from your hosting provider or website administrator and re-install the extension.
You need to try to upload the extension files again and re-install the extension. If it doesn't solve the problem, try to use another installation type (Extension Installer, VQMod, Marketplace).
