Hi. I have started having trouble accessing some pages that I have reached easily in the past. When I enter the website address, I get the following..

The MediaWiki logo MediaWiki 1.31 internal error

Installing some PHP extensions is required. Required components

You are missing a required extension to PHP that MediaWiki requires to run. Please install: 

   mbstring (more information)
   iconv (more information)
   fileinfo (more information)

- an example of the address that produces this result is:

https://wiki.apterous.org/Episode_8050

I am not sure what has gone wrong, or how to fix it. I tried clicking on 'more information' and found some alarming technobabble way beyond my limited comprehension. What is 'mbstring' 'iconv' and 'fileinfo'? - and how do I 'install' them? This site has worked in the past, so I am mystified. Thanks for any help. - John

Hi, PHP extensions are a server-side feature and you would expect to see this in all browsers if the message is true. If there is a difference between the errors in Firefox and other browsers, a file might be blocked from loading by Tracking Protection or an add-on.

Many thanks for your precise accurate help. I re-installed microsoft edge on my laptop and confirmed that the problem occurs there as well. So I will take this problem up with the content provider to find out what is going on. - John
