HI Mehtaz Afsana Borsha, thank you for your message. I checked the advice in the FAQ, but it didn't solve my problem. My value max_file_uploads is 20M but I am trying to upload images that are 100-200kb in size. If I upload a photo via Article -> Media, it appears in the joomla directory. If I want to add a photo to an article via the Blog Media tab, the thumbnail is not displayed in the panel and in the article on the front page. I tested it on different servers and different websites built on the Helix Ultimate template (Joomla 3 and 4.x) and I always get the same error.
On every page where the php 8.x version works, adding photos in the Blog Media tab does not work. Please help because this is a big bug that stops our work.
