Hi Elliot,
Sorry, I didn’t post since 2 weeks.
My hosting is a shared hosting at OVH and external calls from a website pass by several proxies which IPs are different from the website’s hosting.
For security reasons on this kind of hosting OVH doesn’t allow any changes.
In this case Curl calls can’t work.
If I want it works, I must change virtualized hosting.
Also, I’ll manually update ACF PRO.
Thanks.
