@esiao That didn't worked, it looks like it doesn't even loads masonry.js for some reason. How can I see is the scirpt loaded and is it loaded correctly? Maybe some cmd command? I followed all instructions in setting up plugin.json and theme.json and I am pretty sure that I did it right. I can't figure out what can be the problem. Any other suggestions?
Tnx anyway ^^
In my topic.tpl I made some changes using @first to separate first post in topic from others. It worked, but there is now next problem. When i create a new post it doesn't show it instantly, I have to refresh page to see that post.
