Upload image with editor

hello can you help me understand why in an installation of ojs 3.4.0-8 I have the upload image button and on another not?
I’m going crazy


just today trying to update the tinymce plugin this error came out

fixed the error by inserting now the upload appeared and it works
application::SITE_CONTEXT_PATH
this variable is null

This happens because the TinyMCE plugin doesn’t add the uploadUrl to the plugin settings when no context is available.

which uploadurl should i put?

there is this old post

with my same error.

is there a solution now?
