Hi,

I updated Wordfence and suddenly am getting the following error but even after uninstalling Wordfence it's still happening, I also restored a backup but it's still happening!

For detailed support, you will need to open a topic in the support forum vice pre membership queries.

But it appears that something on your server is blocking the http request to our server that checks if new versions of core, plugins or themes are available.

HAve to wonder if something from wordfence is still hanging on.

All on same server? Did you our host change php versions? Maybe simple xml is not included in current php?

Yep, all on same server. Host didn't change PHP versions and simple xml is included in the current PHP.

It's breaking my Updates via /wp-admin/update-core.php
It's breaking plugin enabling/disabling via: /wp-admin/plugins.php

Disabling Wordfence doesn't resolve it but disabling Simple Press does fix it... sure it's not your end?

Well all I can say there is that it's not a general problem..  Working fine here and on couple other sites I checked.

Additionally, we are getting updates today. Have watched the counter and its increasing. So again generally working. And at least as of now, no other reports.

Looking at your error bit more it doesn't seem to be comm related as I was thinking. It's actually a php error that the class isn't there which is odd. More like a file not found and don't think related to any communication with our server. Rather confusing actually.

Hi Papa,

Could I request Simple:Press to take a look because it should work at all because I know I haven't changed anything in regards to Simple:Press the only change I made was Wordfence and I disabled and uninstalled that but it's still happening.

Take a look at what?

i did review our server and verified its working.  Here and multiple sites and verified uploads occurring.  If general problem it would occur here too. 

If you can post your server IP I can verify its not blocked for some reason. But at 38,000 feet now on plane so won't be able to do that until after I land later this afternoon

Hi Papa,

I logged into my servers SSH and pinged your server and it appears fine, we can ping your server just fine, no packet loss and a response time of 101ms

Really quite confusing.
