Can’t upload files, can’t save settings from frontend, among other things

I’m not sure if I’ve set up Dokan correctly, but after the quick setup wizard process and checking all Dokan pages, my concerns are:

1. Interface of Dokan store (single seller) has all elements seem like not placed in a single container, they’re almost all over the place. I had to fiddle with CSS to pull them together, but it’s not enough because I don’t know much.

2. I can’t save store settings and payment settings as vendor from Dokan dashboard. Every time I click the save button, the page reloads and goes back to the original settings.

3. I can’t upload any photos or files in store settings and during add/edit products from the frontend. It just goes /dashboard/settings/store/# or dashboard/new-product/#. I can only upload files when I give access to wp-admin dashboard area to edit products. But when I upload images, they automatically become WooCommerce image placeholders right after upload to media library.

4. I can’t publish new products as vendor without having the admin preview and publish it. I tried checking the Allow newly registered vendors to add products in Vendor capability, the product is still pending for publish. I tried unchecking it- the vendor can create product, still pending.

This plugin seems really great and simple to use compared to other multi-vendor marketplace plugins out there, so I really hope to hear from you regarding this. Thanks!
