To install new addons in PixelPost, you should first download their installation packages.
Next, extract them to a folder in your computer and upload all the files and folders of the extension in your PixelPost directory. Depending on the package itself you may have to upload only few files in the “addons” folder or to several other directories. It is important to follow the instructions in the Addon documentation in order to install it correctly.
Once you have uploaded the files for the addon, login to your administrative are and go to the Addons tab. The new addon will be listed as disabled (showing “status: OFF” next to it). You can enable it by clicking on the “Off” link next to it.
