Hi Gyula,

The error you’re encountering indicates an issue with the tempera/includes/theme-setup.php file in your WordPress Tempera theme. Specifically, the error suggests there is an issue with the sprintf function in the theme’s code. This is likely due to changes in PHP’s handling of format specifiers in version 8.1+.

Here’s how you can resolve it:

—

### **1. Identify and Fix the Code Issue**
The error message points to line 284 of theme-setup.php. The sprintf function is likely using an invalid or undefined format specifier.

– Open the file /var/www/html/wp-content/themes/tempera/includes/theme-setup.php in a code editor.
– Locate line 284 and review the sprintf statement.
– Check for any empty or invalid placeholders in the function, such as % without a type specifier (s, d, etc.).

For example, if the code looks like this:
`php
sprintf(“Hello, % !”, $name);
`
It should be corrected to:
`php
sprintf(“Hello, %s!”, $name);
`

### **2. Temporary Workaround**
If fixing the code directly isn’t feasible (e.g., you lack access or time), you can switch to another theme temporarily:
1. Access your WordPress installation through **FTP** or the **file manager**.
2. Navigate to /wp-content/themes/.
3. Rename the tempera folder to tempera_backup.
4. WordPress will automatically switch to a default theme like Twenty Twenty-Three.

—

### **3. Update or Replace the Theme**
The Tempera theme may not be fully compatible with PHP 8.1+. To resolve this:
1. **Update the Theme:**
– If there’s an updated version of Tempera, install it.
– Download updates directly from the theme developer or WordPress repository.
2. **Switch Themes:**
– If the theme is no longer maintained, consider switching to a more modern theme with PHP 8.1+ compatibility.

### **4. Downgrade PHP (as a Last Resort)**
If updating or fixing the theme isn’t possible:
1. Downgrade to PHP 8.0:
– PHP 8.0 supports both Nextcloud and WordPress.
2. Install PHP 8.0:
`bash
sudo apt update
sudo apt install php8.0 php8.0-fpm php8.0-mysql php8.0-xml php8.0-mbstring
`
3. Restart your server:
`bash
sudo systemctl restart apache2
`
4. Verify the PHP version:
`bash
php -v
`

### **5. Debugging and Logging**
Enable WordPress debugging to capture more detailed errors:
1. Edit your wp-config.php file and add the following:
`php
define(‘WP_DEBUG’, true);
define(‘WP_DEBUG_LOG’, true);
define(‘WP_DEBUG_DISPLAY’, false);
`
2. Errors will be logged in /wp-content/debug.log.

—

### **6. Contact the Theme Developer**
If the theme is actively supported, contact the developer for an update or guidance. Provide the error details to expedite a solution.
