📌 Overview
OTTO works on a set number of site slots. Each site you activate with OTTO uses one slot. If every slot is in use, or a slot hasn't been released yet, you won't be able to add another site until space is available. This article explains how slots work, why a replacement site may be blocked, and what to do next.
❓ The Most Common Question
Customers often tell us: I removed a site from my projects and portfolio and tried to add a new site to replace it for OTTO, but the platform won't let me add it.
This is expected in some cases. Removing a site from your projects or portfolio list does not always free up its OTTO slot right away. The slot can stay assigned to the original site, so the new site is treated as an additional one.
🔍 How OTTO Site Slots Work
- Your plan includes a specific number of OTTO site slots.
- A slot is used when a site is activated with OTTO, not only when it appears in your projects list.
- Deleting a project or portfolio entry is not the same as releasing the OTTO slot it was using.
- If all slots are in use, you need to free a slot or add capacity before activating another site.
🧩 Why You May Not Be Able to Add a Replacement Site
- The old slot is still assigned. The removed site may still count toward your OTTO allowance.
- You've reached your plan limit. All included slots are in use, so a new site can't be added.
- A top-up is required. If you need more sites than your plan includes, extra slots must be added to your account.
- The change hasn't updated yet. Slot counts can take a short time to refresh after a site is removed.
🛠️ What to Try First
- Refresh the page, or log out and back in, to make sure your account shows the latest information.
- Check your plan and billing settings to see how many OTTO site slots you have and how many are in use.
- Review your active OTTO sites and confirm which ones are using slots.
- Make sure the site you removed is fully deactivated in OTTO, not just removed from the projects list.
- Try adding the new site again.
💳 When a Top-Up Is Needed
If all of your slots are in use and you want to keep every site active, you'll need a top-up to add more OTTO site slots. A top-up increases the number of sites you can run on OTTO without replacing an existing one.
You'll likely need a top-up if:
- You want to add a new site without removing an existing one.
- Your removed site's slot isn't being released and you still need the new site active.
- You are managing more sites than your current plan includes.
🔄 Swapping One Site for Another
If you want to replace one site with another and stay within your current plan, follow these steps:
- Deactivate OTTO on the site you no longer need.
- Confirm the slot count has updated on your account.
- Add the new site to your projects.
- Activate OTTO on the new site.
If the slot doesn't free up after these steps, the account may need a manual check by our team.
💡 Tips to Avoid Slot Issues
- Check your slot usage before planning to add or replace sites.
- Deactivate OTTO on a site before you remove it from your projects.
- Allow a little time for your account to update after making changes.
- Plan ahead if you expect to manage more sites, so you can add a top-up in advance.
