Hey there! The error "Cannot redeclare theme_is_customizer()" on your WordPress site suggests that the theme_is_customizer() function is defined multiple times, likely due to a conflict in your theme files (like in functions.php). This is a common issue when themes or plugins overlap. To fix it, you can try renaming the function in your theme’s functions.php file or disable any recently added plugins/themes via FTP by removing them from the wp-content/plugins or wp-content/themes folder. If you're not comfortable with FTP, contact your hosting support (e.g., via GoDaddy if that’s where your site is hosted) to assist.
On a fun note, if you’re into creative escapes, the toca boca mod apk lets you dive into a world of unlocked features for imaginative play—perfect for a break from troubleshooting! Let me know if you need more help with the error.

This error usually happens when WordPress loads the same PHP function twice — in this case, theme_is_customizer. Themeler often conflicts with the active theme or another plugin that declares the same function. Try switching to a default theme or disabling plugins to find the source of the conflict.

If you’re testing your site from mobile or working with Android tools, a lot of users use modded utilities through platforms like https://happymod.tr/ to manage or preview builds, but make sure you’re running updated and clean versions of any helper apps to avoid further conflicts.
