Helix3 3.1.4 Featured Image upload broken with Joomla 5.4.8
I am using Joomla 5.4.8 with Helix3 Framework 3.1.4.
Since the latest update, I can no longer add a Featured Image under:
Article → Helix3 Blog Options → Featured Image
When I select an image, the upload progress appears briefly and then disappears. No image appears in the Featured Image field and consequently no featured image is displayed in the article/blog layout.
The image itself IS successfully uploaded to the /images/YYYY/MM/DD/ folder on the server. Therefore the file upload is working, but Helix3 is failing to attach/save the uploaded image to the article.
Helix3 Ajax plugin is enabled.
Blog image dimensions are valid:
Thumbnail 330×183, Medium 850×533, Large 1200×800.
Joomla's Full Article Image works, but this does not replace the Helix3 Featured Image used by our existing blog layout.
This functionality worked normally until the recent update.
Thank you,
Adrian
