@julian Great tips here, thanks.
Redactor client does not display image upload errors from server
I am running the latest nodebb master, and updated to the latest redactor-composer.
I tried to upload a file using redactor, but it did not work, and no error message was posted. With further digging I found that the file was too big (higher than the predefined value in the admin page).
Is there a way to catch and display errors from nodebb callback routed into the Redactor plugin?
Minor issue, I see that when @media width>1000 Redactor is full page, but the topic title placeholder disappears. Further research identified that the div above it has "display = flex". Unsettling that brings back the title placeholder.
