@Ahvca I did the following and was still not able to make the problem go away. I really feel this is not a caching issue.

@Ahvca I will schedule a reboot of the cazypedia server which should flush any caches to confirm that your patch works and let you know.

Any update on your progress?

I have shared the cazypedia php info as a pdf document and the BiblioPlus files via UBC Workspace just like I had previously shared the LocalSettings.php file.

@Ahvca As mentioned previously, the cazypedia server does not run redis. You should reconfigure your development environment to exclude redis. We run simple mysql, php, and apache.

@Ahvca I implemented your change on cazypedia.org, restarted the webserver and tried clearing the cache using this url:
https://www.cazypedia.org/index.php/Help:References?action=purge

@Ahvca were you able to confirm that this fix works in testing?

Sadly we are not running Redis on the cazypedia.org server. This must be getting stuck elsewhere too.

Thanks for posting. Is there anything else you need from me at this moment Alex (@Ahvca) or are you able to continue to debug this on your own?

Whoops forgot to close this issue after Karen had fixed it.

Perfect timing! I just got access to Gerrit and will be pushing an update to the code today and then there is another update planned for changing api access to HTTPS.
