To install Bloqs move the /addons/bloqs/ directory to your /system/user/addons/ folder. Also copy the /themes/user/bloqs/ folder to the /themes/user/ directory in your ExpressionEngine install. Login to your control panel and visit the Developer > Add-ons page, and click the Install link for Bloqs.
Updating Blocks (for EE 2) to Bloqs (for EE 3+)
As a result of the Add-on name change, updating from Blocks (EE2) to Bloqs (EE53) is a tad bit misleading during one part of the process, but rest assured all will work out and you will be up and running in no time.
In the /system/user/addons directory of your (recently upgaded) ExpressionEngine installation, locate and delete the “blocks” folder. This is the old version of Blocks which is only compatible with EE2.
In the /themes/user directory of your ExpressionEngine installations, locate and delete the blocks folder.
Open up the Bloqs package you downloaded in Step 2, and move the /system/user/addons/bloqs folder into the /system/user/addons directory of your ExpressionEngine installation.
Move the /themes/user/bloqs folder into the /themes/user directory of your ExpressionEngine installation.
Now, login to your ExpressionEngine Control Panel and open up the Add-on Manager view.
(Here’s where things are a bit misleading). Locate ‘Bloqs’ in the Third Party Add-Ons list. You’ll notice that it’s grayed out with a button that says “Install” next to it. Don’t panic! If Bloqs was already installed on your EE2 site, it’s still there - you haven’t lost anything. Just click the button that says ‘Install.’
The Bloqs update routine will run and handle the Blocks to Bloqs conversion process.
