From the support folks over at the web host (who also stated there is no extra security on the site)

I have checked the module settings and everything seems to be fine there, I also made a cURL request to the teachinggardenpwc.wordpress.com/feed/ link from your account and it is accessible:

Code:

mgpw3024@siteground247 [~]# curl -IX GET teachinggardenpwc.wordpress.com/feed/
HTTP/2 200
server: nginx
date: Wed, 06 Jun 2018 05:06:28 GMT


I would recommend checking with the module developers for further debugging, if there is anyting they require from us, we will be happy to assist further.

The issue here is that with the same versions and feed I cannot reproduce the error.
Are you getting any errors in your error_log? Eg: timeouts?

The only items in the error log are login failures. Nothing referencing the feed at all.

Joomla version 3.6.5 stable
module version 3.5

I still feel that the error message shown at the top of the page when I open the module is giving us the answer but I don't know what it means: Strict Standards: Declaration of JWElement::render() should be compatible with JFormField::render($layoutId, $data = Array) in /home/mgpw3024/public_html/modules/mod_jw_srfr/includes/elements/base.php on line 17

I have some additional information. I installed another RSS reader on the site and it generates the following error message: Errors:
cURL error 52: Empty reply from server

So googling this comes up with a variety of possibilities. Assuming that your module is getting the same response (I have not found the error logs yet) Is your call specifically to an HTTP site? The blog I'm calling is HTTPS and that would be enough to cause this error. Does your module call out an IP address only? Because that would cause a failure if calling a name based virtual host.

I am not a developer. I have a request into my web host to point me to where the error logs are on the server and maybe some more helpful information will be available. If you have seen this error before and know how to fix it, please let me know.

Thanks

If both Feed Readers fail, then the issue is most likely in your setup.
Are you using any Firewalls or proxies?
Furthermore do you have a test domain/ server to try it there?

I put this out to my Joomla users group and it was suggested that backwards compatibility has been removed from the core Joomla install. I just updated the site to 3.8.8 and that did not fix it. Can you tell me what the latest version of Joomla! your module is compatible with?

Sorry, I did not answer your questions. No proxies or firewalls. I do have a sandbox that I'll look at.

Turns out the server side was running an old version of php. I updated that and it is working correctly again. I'm sharing this here in case it may help someone else. A member of my Joomla! user's group helped figure it out. Bless him.

Thank you for letting us know :)
Which was the outdated version?
