Just wondering if anyone else has had this issue
I am running ACF PRO 5.1.6 and have noticed that if I add an Iframe to a text field and hit update on the post/page it just hangs and gives me a 403 unauthorized error in the console for admin-ajax.php
Just a quick backstory to my setup. So I run my WordPress installs on a vagrant box (in particular using a laravel/homestead box) and it seems to work fine locally. But as soon as I upload to the server it has caused this issue on my last two sites.
It is definitely the iframe in a text or textarea field that is causing the headache on the live server, if I remove it or just use some other random text it behaves fine.
Any suggestions at all, or has anyone else had this issue?
As it turns out my host needed me to add the IP to my /etc/hosts file and point to my domain, as I was using the test url given to me when I setup the account.
So on my shared hosting I had a test url of 126.96.36.199/~testing which works fine, but a recent update to mod_security causes issues if you use this URL and post an iframe into a custom text field. It triggers a 403 error and some sort of CORS issue arrises.
I’m really clueless with sysadmin so a quick call to my host was able to sort this out for me.
Moral of the story if setting up a testing url with a shared host, add that IP to your local /etc/hosts file to get rid of any headaches and that will make the site behave as expected, for example if you setup a new account for testing.com and get given a temporary url of 100.100.11.11/~testing edit your /etc/hosts file to have 100.100.11.11 http://www.testing.com testing.com
I hope this helps someone else who isn’t great with sysadmin like me.
Thank you for sharing this 🙂
Quite a big help when interacting with sysadmin.
