# Theme could not be assigned to sales channel

## Description

When assigning the theme to a sales channel, the error message "**Theme could not be assigned to Sales Channel.**" appears.

## Cause

Unfortunately, the error message is not very significant. A more detailed error message is needed to solve the problem.

## Solution

How to get a detailed error message please find in the article [Debugging error messages](/knowledge-base/tutorials/debugging/debugging-error-messages.md).

{% hint style="info" %}
**Note**: In our experience, the **PHP memory\_limit** is usually the cause of such problems. More information can be found in the article [Allowed memory size of ... bytes exhausted](/knowledge-base/common-issues/administration/allowed-memory-size-exhausted.md).
{% endhint %}
