Sergio Izquierdo
Hello I am having problems when changing settings of a template style (bungkoh). I have php 8.1, joomla 5.2.3, helix 2.2.4. When trying to save it says "Error Undefined". There is no error reported in apache or in Joomla. These are the file permissions:

Accepted AnswerHello,
Thanks for reaching out to us. Could you please share temporary administrator access to your Joomla backend? You can provide the credentials securely in the hidden content section. Also, please take a full backup of your site before we make any changes.
Once I have access, I’ll investigate further and see what’s causing the issue. Let me know once you’ve shared the details!
Best regards,

Accepted AnswerHello,
I see the issue only on your live site, it does not appear on my local setup. It is likely that your live server has caching enabled (via cPanel, plugin, or server-level cache) or there may be firewall rules / ModSecurity that are preventing template styles from saving correctly.
Please contact your hosting administrator to:
- Clear all caches on the server.
- Temporarily disable any WAF rules or ModSecurity settings to test saving template styles.
This should help identify whether these server-side protections are causing the issue.
Thank you,
Sergio Izquierdo
Accepted AnswerThank you for your help.... All caches are emptied, I dont have de ModSecurity available in Cpanel. It does not let me paste my ,htaccess file in case in hidden content so you can check it out. When clicking "Post Answer" it takes for ever. I have this as part of .htaccess: ########## Begin - SP Page Builder RewriteRule ^administrator/components/com_sppagebuilder/(.)$ - [L] RewriteRule ^components/com_sppagebuilder/(.)$ - [L] ########## End - SP Page Builder thanks Sergio
