GPT:

The errors you're encountering are PHP warnings and they can give you clues on how to fix issues in your code. Here's a breakdown of each:

### 1. `sprintf(): Too few arguments`
The error `[phpBB Debug] PHP Warning: in file [ROOT]/ext/steve/postreactions/notification/type/reaction.php on line 95: sprintf(): Too few arguments` suggests that the `sprintf()` function is expecting more arguments than what has been provided.

**Possible Solutions:**
- Check what the `sprintf()` function at line 95 in `reaction.php` is expecting and make sure all required variables or values are passed in.
- Alternatively, wrap the `sprintf()` in a conditional to ensure all required arguments exist before calling it.

### 2. `Cannot modify header information - headers already sent by...`
The series of `Cannot modify header information` errors indicate that some data has been sent to the browser before you tried to send additional HTTP headers.

In PHP, headers must be set before any output is generated, so even a single space or a line break can cause this error. This issue is common when you have PHP mixed with HTML and you accidentally add whitespace.

**Possible Solutions:**
- Identify what's being sent to the browser by looking at the line where the error originates. In your case, it is `[ROOT]/includes/functions.php:3009`. Check if any output (even whitespace) is being sent before you try to set headers.
- Use output buffering functions like `ob_start()` at the beginning of your script to capture output and then use `ob_end_flush()` or `ob_end_clean()` to send the output when ready.

### Additional Debugging Steps
1. **Check Error Logs**: Your server should have error logs that provide more context around when and why these errors occurred.
2. **Check for Modifications**: If you've recently modified or extended the phpBB code, undo or review those changes.
3. **Update and Patch**: Make sure you're running the latest versions of phpBB and PHP itself, as patches often contain fixes for issues like these.

For further information on these functions and errors, you can refer to the official PHP documentation:
