Uppy file uploader and proxy = headache

Robert AndresenProgramming Leave a Comment

The browser returned a CORS-error and Uppy itself returned a network traffic error. 99% of all issues and google-results pointed to an api/server issue with my headers. The weird part was …

Using Adldap2

I have been using Adldap v4.x at my work for a while now. After installing a test-server with PHP7, I found that the Adldap needed to be updated.
