This works exactly like installing any other WordPress plugin. Two minutes, no developer, and your website stays online throughout.
What you need in front of you
The plugin file you downloaded (a .zip file), and your WordPress login as an administrator.
Step 1: Find the file
After your purchase you got an email with a download link, and the file is also in your account on our website.
Download it. Your browser almost certainly put it in your Downloads folder. It is called something like houzez-mollie-payments.zip.
Do not unzip it. WordPress wants the .zip exactly as it is. Unzipping it is the single most common installation mistake.
Step 2: Upload it
Log in to your WordPress admin, which is your website address followed by /wp-admin.
In the left menu, click Plugins, then Add New Plugin.
At the top of the page, next to the heading, click the Upload Plugin button.
Click Choose File, pick your .zip, and click Install Now.
Wait a few seconds. WordPress does the rest.
Step 3: Activate it
When it finishes, WordPress shows a link that says Activate Plugin. Click it.
People forget this step surprisingly often, then wonder why nothing happened. An installed plugin that is not activated does nothing at all.
How to tell it worked
Look at the left menu of your WordPress admin. There is a new item called Mollie Payments, sitting just below Houzez.
Click it. The plugin opens on the License tab, and near the top you will see a small badge telling you that no API key has been added yet.
That is exactly right. You have not connected Mollie yet, and the plugin is being honest with you.
If the upload fails
Some hosts limit how big an uploaded file may be, and our plugin may be larger than that limit.
If you see a message like “the uploaded file exceeds the upload_max_filesize directive”, that is what happened. Email your hosting provider and ask them to raise the upload limit. It takes them a minute.
Alternatively you can install over FTP. If that sounds like a foreign language, send us a message. We will do it with you, and we will not make you feel silly about it.
What happens next
The plugin is installed, but it is still asleep. Activating your license wakes it up.
