After moving to a lower Discount Mixer plan, some campaigns may use features or exceed campaign limits that are not available on your current plan.
To activate the campaign again, open it and review the restriction message. Depending on the message, you may need to change an unavailable feature, reduce the number of active campaigns, update expired dates, or upgrade your plan.
How to find out why your campaign cannot be activated
From your Shopify admin, open Discount Mixer.
Select Campaigns.
Find the campaign you cannot activate.
Check its current status and any plan-related indicators displayed next to it.
Open the campaign.
Review the restriction message in the campaign editor. It explains what is preventing activation and may show which plan supports the current configuration.
Plan-related indicators help identify campaigns that require changes.
Open the campaign to see which feature or plan restriction is preventing activation.
Note: Restricted campaigns do not always display the same indicator. This is especially true for campaigns that were already inactive or expired. Open the campaign and review its restriction message to confirm the cause.
If your campaign uses a feature that is unavailable on your plan
A campaign may stop being available for activation if it contains a feature that your current plan does not support.
To fix it:
Open the affected campaign.
Find the feature marked as unavailable for your current plan.
Remove the feature or replace it with an option supported by your plan.
Save the campaign.
Try to activate it again.
If you want to keep the existing configuration, use the upgrade option shown in the restriction message to move to a plan that supports the feature.
If you have reached your active campaign limit
Each plan supports a specific number of active campaigns. If your current plan’s allowance is full, you cannot activate another campaign.
On the Campaigns page, you may see a Campaign Limit Reached message showing your current number of active campaigns and your plan limit.
The Campaign Limit Reached warning appears when your active campaign allowance is full.
To resolve the restriction:
Review your active campaigns.
Deactivate an active campaign that you no longer need, or select Upgrade to increase your allowance.
Return to the campaign you want to use.
Try to activate it again.
You can also select Contact support if you need help choosing the appropriate option.
You may also see the restriction inside the campaign editor:
The campaign edit page shows when the active campaign limit prevents activation.
What happens to existing campaigns after a downgrade?
The outcome depends on the campaign’s status before the plan change.
Active or scheduled campaigns
If an active or scheduled campaign uses a feature that is unavailable on the new plan, it may become inactive.
Open the campaign, review the restriction message, and update the unsupported configuration before activating it again.
Inactive campaigns
An inactive campaign remains inactive. If it uses unavailable features or your active campaign allowance is full, you must resolve those restrictions before activating it.
Expired campaigns
An expired campaign remains expired. It cannot be activated until its dates are valid and any plan restrictions have been resolved.
How to reactivate an expired campaign
An expired campaign may have more than one activation restriction. Updating its dates alone may not be enough.
To reactivate it:
Open the expired campaign.
Change its end date to a valid future date.
Review the restriction message in the campaign editor.
Remove or replace unavailable features.
If your active campaign allowance is full, deactivate another campaign or upgrade your plan.
Save the changes.
Activate the campaign again.
Final checks
If the campaign still cannot be activated, confirm that:
Its start and end dates are valid.
It does not use features unavailable on your current plan.
Your active campaign allowance is not full.
All changes have been saved.
If you still need help, select Contact support from the restriction message or contact the Discount Mixer support team.
