About my case, it isn’t about a wrong or invalid activation code since its working in my local environment and on other hosts that OVH.
Actually, fields are working (I’m always using the acf-json folder and/or generated code to import the field), I just can’t activate my license thereby update the plugin. So this doesn’t stop me from using the plugin.
I also have the exact same issue with the same host (OVH).
For what I tried, I don’t think it’s related to my theme, neither to any corrupted files and I hadn’t any issue in my local env.
(OVH is using http://php-fpm.org/, also tried to disable it and set different Php version but still unsuccessfully)
Any help would be greatly appreciated 🙂
