Hello,

You have already gone through several common troubleshooting steps for dealing with the theme customization hang issue on your multisite setup. Since you’ve followed those steps without success, here are some additional things you can check or try:

1. Check for PHP Version Compatibility
   Reason: WordPress and themes/plugins can sometimes have issues with certain PHP versions, particularly if you’re using an outdated or unstable version.

Solution: Check your PHP version (preferably PHP 7.4 or higher for WordPress). If you’re running a much older version, try updating to a supported PHP version and see if the issue persists.

2. Increase PHP Max Execution Time
   Reason: If the theme customization requires more time than the server is allowed to allocate, it can lead to a hang.

Solution: Increase the max_execution_time in your php.ini file to 300 or more:

max_execution_time = 300
If you don’t have access to php.ini, you can try adding this line to your .htaccess file:

php_value max_execution_time 300

3. Check Database Performance and Size
   Reason: Large databases or inefficient database queries might cause slowdowns or timeouts during theme customizations.

Solution:

Run database optimization and repair processes. You can do this via plugins like WP-Optimize or through phpMyAdmin by running the OPTIMIZE TABLE command.

Check the wp_options table for large entries in the theme_mods_ and wp_site options, as these could impact the customizer.

4. Disable Object Caching and Persistent Caching
   Reason: In multisite setups, caching systems like object caching or persistent caching may store old data and cause issues during theme customization.

Solution: If you have object caching enabled (e.g., Redis or Memcached), try disabling it temporarily. You can do this by either:

Disabling it from your caching plugin settings.

Adding this line to your wp-config.php:

define(‘WP_CACHE’, false);

5. Revert to Default Theme Customizer Settings
   Reason: Customizer issues can sometimes be caused by custom theme customizer settings or changes in your theme’s functions.php.

Solution:

Temporarily remove or comment out any customizer-related code in your theme’s functions.php file to see if it’s causing the issue.

If that resolves the issue, you can narrow down which part of the customizer is breaking.

6. Ensure Network-wide Theme Activation
   Reason: Sometimes, the issue can be due to incorrect theme activation at the multisite level.

Solution: Ensure that the theme is properly activated network-wide and is available for each individual site. You can check this from Network Admin > Themes.

7. Inspect the wp-config.php and .htaccess Files
   Reason: Misconfiguration in wp-config.php or .htaccess could be causing issues during theme customization in a multisite.

Solution: Double-check your wp-config.php for any incorrect multisite configuration. Pay attention to:

SUBDOMAIN_INSTALL (whether you’re using subdomains or subdirectories).

DOMAIN_CURRENT_SITE (ensure it’s pointing to the correct domain).

You can try adding this in your wp-config.php to enable multisite debugging:

define(‘WP_ALLOW_MULTISITE’, true);

8. Test the Theme on a Fresh Multisite Installation
   Reason: The problem might be specific to your current multisite installation.

Solution: Create a new test multisite network (either locally or on a staging environment) and install the theme there to see if the issue still occurs. This can help isolate whether it’s a network-wide problem or related to the current configuration.

9. Review the Theme’s Customizer Code
   Reason: Customizer functions in your theme’s functions.php file may have issues when used in a multisite context.

Solution: Review any add_theme_support, customize_register, or other custom customizer hooks to see if they might be misconfigured for a multisite setup. Temporarily disable custom customizer additions in your theme to see if that resolves the issue.

10. Check the Server’s Resource Limits
    Reason: Hosting environments, particularly shared hosting or those with strict limits, can sometimes restrict certain actions, leading to hanging or login Illinois Tollway slow loading times.

Solution: Contact your hosting provider to ensure that your server is not hitting any resource limits (like CPU usage, memory, or concurrent processes) when you’re trying to customize the theme.

Best Regard,
