Hi Stefan,
Thank you for reaching out and providing the details.
The issue you're encountering with the SP Page Builder 5.5.2 Front-End Editor not rendering images correctly under a multi-language setup is related to how relative paths are handled in such configurations. When using multi-language structures (e.g., /en or /de in the URL) combined with a Joomla installation in a subdirectory, the editor may misinterpret relative image paths, leading to the broken image symbol you’re seeing.
Solution:
To resolve this, please use the full URL for images within the Text-Block add-on. For example:
<p>Lorem ipsum dolor sit amet...</p>
<p><img src="/www.examplehost.com/myjoomla/images/banners/banner.jpg" alt="banner"></p>
<p>Lorem ipsum dolor sit amet...</p>
By specifying the full path, the Front-End Editor will correctly render the image regardless of the language URL structure or subdirectory installation.
Let me know if this resolves the issue or if you need further assistance.
Best regard
