You’re welcome Howard. Let me know if you have any suggestions. The admin user case fix is in this image as well.

Hi, James,
I am still unable to successfully download the “en-Fantastic Phonics” modules (adult and child).

I also had trouble getting the en-wikitionary module to get the href
to the search index right. I had to correct the index file name.

Thanks for the good work. We will be using this in Uganda.

Hi @chuckroast,

You’re welcome and I’m happy to help! That’s great to hear that you’ll be using RACHEL-Pi in Uganda.

I will download and take a look at en-wiktionary to see what the issue is and a fix for it. It will be tomorrow in about 12 hours or so as the internet is a bit slow here right now. Hopefully there’s a quick fix.


@chuckroast - I have downloaded en-wiktionary and everything seems to be working on my end. Did you install through the admin user interface or through a transfer directly to the device?

James, Sorry. It wasn’t Wiktionary, It looks like Wikihow searches aren’t happening
in the front menu or internal menus. I tried “Family” in
the front menu, “Dogs” from the Pets page, and under Philosophy I tried “atheism”. “Suggestions” drop down when entering, but no
results after pressing the enter key.

Hi @chuckroast,

No problem. Are you using “en-wikihow” or “en-wikihow-static”?

Also just to confirm, is the search bar that’s not working or is it the preset categories that are in a list on the RACHEL page?


Thanks for the reply, James.
I believe the full en-wikihow. It’s the search bars.
The preset links work fine.

One other question: If I just manually copy en- modules up to /var/www/modules is there a way to kick off an index scan so that the new module is indexed properly in the home menu?

You’re welcome @chuckroast. I’ll have to download this to see what’s up. I have en-wikihow-static and the search index works in that for me but maybe something is different in en-wikihow. Since it’s 13GB it will probably be a while.

There should be a tutorial called “Transferring modules with WinSCP” included with the image in the Tutorials>Advanced folder that covers transferring things to the device. It’s probably best to do it that way because you’ll want to run “sudo chown -R www-data:www-data /var/www/modules/the_module_name” so it can be deleted at any time in the web interface. If it’s a Wikipedia module you can run the command “sudo systemctl restart kiwix” to update the Kiwix library or you can hide any module in the “modules” page and then hit save. That should trigger one as well.


Hi @chuckroast,

I finished downloading en-wikihow. I notice what you said about many of the results not working. I think this is an issue with the .zim file that it uses. I’m not sure how it was made as it doesn’t seem to exist anywhere else so someone must have manually made it for RACHEL. I don’t think it can be fixed without redoing this process.

I think the solution to this is to use “en-wikihow-static” instead which you can find on the FTP or at en-wikihow-static.zip. I searched “family” with it and it seemed to work and show the results. The rachel-index.php for en-wikihow-static has an issue with the main page links as it has “%3A” in place of the “_” character breaking them. You can either open the rachel-index.php file and replace the %3A with _ or I can upload one for you if you decide to go this route.


“en-wikihow-static” it is…But there isn’t a “en-wikihow-static” on
the drop list under the “install” function yet.
Guess I will have to download it directly. Ooops. There isn’t a
static version at oer2go either!
Could you put one up?

Thanks for your work, James!

You’re welcome @chuckroast. I don’t have access to oer2go or the server to change any content as I maintain RACHEL-Pi as a volunteer. The link I provided above is the only place that I know has it.


Wikipedia for Schools doesn’t install correctly. I can’t
get to links beyond the front page. I installed it from
the RACHEL admin: “install” drop list.

en-WikiBooks links at the top of the main page are inactive, except for the “How To Use”. i.e. “Browse”. Only the Search Bar works. So that one’s out, too

I’m going to revert kiwix-tools to an old version to support the zims. I’m testing a fix right now and will give that to you and put up a new image once I’m sure it works.


This will install an older version of Kiwix and an updated script.

  1. Connect your RACHEL-Pi to an internet connection

  2. Download fix-kiwix.zip

  3. Unzip it and transfer it to /var/tmp on your RACHEL-Pi so you have /var/tmp/fix-kiwix

  4. Connect to the pi overSSH or locally

  5. Run command “cd /var/tmp/fix-kiwix”

  6. Run command “sudo python3 fix-kiwix.py”

  7. When it finishes run command “sudo systemctl restart kiwix”

That should fix the issues with wikipedia modules. Hopefully that works for you.


WikiBooks: Bad href on the title.
(/wikibooks_en_all_novid_2017-07/) not found.

Search bar works fine, now, tho. Thanks!
