In order to test and apply your htaccess rules, I made a clean (ojs 3.2.1.2) install at; https://www.cancer-research.net
I set up 4 journals, 3 having its own domain.
I am actually at the same point where I left, but I can modify settings, submit articles, and publish issues.
When I try to upload a homepage image or journal thumbnail at Website Settings → Appearance → Setup page, I get en error. The error is “Failed to load resource: the server responded with a status of 403 (Forbidden)” with the link to https://www.adlibilimler.online/jfs/api/v1/temporaryFiles
When I click the link, I get {"error":"api.404.endpointNotFound","errorMessage":"The requested URL was not recognized."}
message in a blank white page.
I’ve never felt so close to the solution before.
But I am not a programmer and can’t go any further.
If anyone help with this, I will be very grateful and will share the solution for others to benefit as well.
I may send any user credentials via personal message if needed.
Best regards,
