Reply To: Getting error when vendor upload picture

@hrbang
This happens usually due to one of several reasons.. since you are not using SSL, I’ll skip those debugging steps.

Looking at your wc system status, I’d recommend that you start by deactivating these two plugins:

Simple Local Avatars: by Jake Goldman
10up – 2.0

WP User Avatar: by flippercode – 2.0.8

Now test by logging in as a vendor and trying to upload your banner and icon. If that does not resolve the issue, deactivate all plugins except woocommerce, WC Vendors and WC Vendors pro- then test. If it persists, then switch to the Storefront theme, and test again. https://wordpress.org/themes/storefront/

Let me know if any of these steps help isolate the issue.
