Buongiorno,
quando da wordpress cerco di fare edit in themler mi fa questo errore;
The theme name may contain only alphanumeric symbols and underscore (A-z, 0-9, '_').

Please rename 'ciao/ciao' and 'ciao/ciao_preview' to the fitting name. Also you need to ensure that your name and 'Theme Name' in style.css are the same.

ma il template si chiama solo "ciao"

cosa posso fare?

grazie..

Hello,

Do you have theme installed on your host? In this case please check it via any FTP client, that the theme is installed at the location /path_to_wordpress/wp-content/themes/
where /path_to_wordpress/ is the location of your WordPress installation on the server. Make sure there is no extra subfolder with the same or similar name inside /themes. If there is some confusion, try to remove the previous theme, then re-export and install the theme by following this article:

wp-content/themes/ciao/ciao

ma ora togliendo la cartella e facendo wp-content/themes/ciao funziona!

grazie..

Ciao! The error you’re seeing happens because WordPress requires theme names to contain only alphanumeric characters and underscores. Even if your template is called “ciao,” it’s important to make sure the folder names and the Theme Name in style.css match exactly and follow the allowed format. So, renaming the folders to something like ciao_theme and updating the Theme Name accordingly should solve the problem. Also, double-check that there are no spaces or special characters in any of the theme files or folders. If you’re interested in exploring advanced customization options or managing root access for testing themes safely, you might want to check out magisk alpha zip, it offers powerful features that can help enhance your Android experience while experimenting with different apps.

The error you are seeing in Themler is usually caused by a mismatch between the theme's folder name and the "Theme Name" declared in your style.css file. WordPress requires these names to be identical and strictly follow the alphanumeric and underscore (_) rule; even a single space or a slash (/) will trigger this validation error. To fix this, rename your theme folder via FTP or File Manager and ensure the header in your style.css matches that exact name without any special characters.

Buongiorno

Questo errore di solito compare quando il nome della cartella del tema contiene caratteri non validi o una struttura non corretta. Anche se vedi “ciao”, probabilmente dentro /wp-content/themes/ hai una cartella tipo ciao/ciao oppure con qualche simbolo non supportato.

Prova questi passaggi:

Vai in /wp-content/themes/ e assicurati che il nome sia solo ciao (senza sottocartelle duplicate)
Controlla il file style.css e verifica che il campo Theme Name sia esattamente uguale
Evita slash o caratteri speciali, usa solo lettere, numeri o underscore

Dopo aver corretto, riattiva il tema da WordPress.
