Editing A2HostingEnvironment (section)

===June 5===
I found [https://www.siteground.com/kb/how_to_change_my_mediawiki_logo_image/ this URL] useful as I attempted to change my MediaWiki Logo image.

Via a cPanel-Terminal session, I changed directory to "~/public_html/SelfGravitatingFluids" and &hellip;
<ol>
  <li>Found <font color="green">index.php</font>; its contents were not immediately useful.</li>
  <li>Found <font color="green">LocalSettings.php</font>
  <ol type="a">
    <li>$wgServer = "https://tohline.education"</li>
    <li>$wgScriptPath = "/SelfGravitatingFluids"</li>
    <li>$wgResourceBasePath = $wgScriptPath</li>
    <li>$wgLogos = [ '1x' => "$wgResourceBasePath/resources/assets/wiki.png" ];</li>
  </ol>
  </li>
</ol>

I realized that, when using the cPanel-File_Manager, I must click on the **name** (e.g., SelfGravitatingFluids) of a directory folder as well as the tiny folder icon in order to see all of the directory's files and sub-directories.

[[File:RmodeImage5big.png|right|200px|r-mode image (300 x 300 px)]]

I successfully uploaded the "r-mode image" &#8212; shown here, on the right &#8212; from my Mac to the a2Hosting file system.  

<ol>
  <li>It is 135 x 135 pixels, which is the size used for the replacement MediaWiki Logo; actually, what is displayed here is a 300 x 300 pixel image.</li>
  <li>From the a2Hosting's cPanel, I double-clicked on the "File Manager"; I located the file under public_html/SelfGravitatingFluids/images/8/8b; actually, the displayed image is in ~/images/9/97</li>
  <li>Now, let's try opening the <font color="green">LocalSettings.php</font> file and changing the $wgLogos specification to read:<br />$wgLogos = [ '1x' => "$wgResourceBasePath/images/8/8a/RmodeHBookImage6.png" ];</li>
  <li>That did not work, but the following did:<br />$wgLogos = [ '1x' => "images/8/8a/RmodeHBookImage6.png" ];</li>
  <li>I added the "Self-Gravitating Fluids" label to the same image, then repeated the above-enumerated upload steps.  Now the appropriate Logo can be found at the following location:<br /><font color="red">$wgLogos = [ '1x' => "images/d/d3/RmodeImage8.png" ];</font></li>
</ol>

Where do new MediaWiki pages get stored?
<ol>
  <li>Looks like one ''test'' example is at:  ~/www/SelfGravitatingFluids/tests/phpunit/includes/page/</li>
  <li>Perhaps the real thing is at:  ~/www/SelfGravitatingFluids/includes/page/</li>
  <li>Even more likely to be useful:  ~/www/SelfGravitatingFluids/includes/content/<br />
<font color="maroon">88% into ''TextContent.php'' &hellip;</font> "Generates an HTML version of the content, for display.  Used by fillParserOutput() to provide HTML for the ParserOutput object."
  </li>
</ol>
