been goin through some of the posts on forum here and didn’t find any close to the matter. So, several months ago I’ve setup a page for my client relying heavily on ACF Pro. Everything worked like a charm. Fast forward to one month ago, he asked me to move all of his stuff to another hosting – that went well too. Fast forward again, today I was asked to update just one thing, just some random quote string to be displayed on the front. Everything was already setup previously, typed it, clicked Update and boom, 403 Forbidden | nginx
Tried that several times, went to debug.log (no info there). All the fields are grouped up by pages, I’ve discovered that on some of them Update option works just fine whereas on the others I’m getting 403. Been trying to find out what’s the cause for that but I’m kinda stuck, not sure even where to look for the info.
All of the fields are working just fine (functionally), all the data is there. It’s just, some of it cannot be updated. Any ideas? Is there any way to check up what’s wrong with the given field? Shouldn’t the debug.log provide some basic info? is it just hosting related (mod_security?)
I would say that there is something in a firewall on the server that is doing this. You need to narrow down what type of field and what the content is that is causing it. Then you can have a discussion with the hosting company to find a solution.
