Trying to use “Edit Page” in the “wp-admin” panel but with difficulty!

I’m trying to use the editor tool “Edit Page” in the WordPress interface, but it seems very cumbersome to use! When I try to highlight a block of text (in order to change the font to a different font) nothing is highlighted — it seems that the selection function/highlighting is not working at all. I can type in a new hyperlink on the page, but I can’t seem to select any text.

I just installed a fresh WordPress 6.2.6 site to test this out, no plugin installed, and only the default Twenty Twenty-Three theme.

Even with no third-party code, I was unable to select anything in the default block editor. I switched to different default themes, but that didn’t help. Only upgrading WordPress fixed that.

So, it seems, the solution to your editor text selection issue is to upgrade WordPress.

The WordPress version being used is 6.2.6. (It won’t update, because it tells me that the PHP version must be updated first, and the PHP update is disabled.)

Your site is running PHP/5.6.40, which even the most die-hard “If it ain’t broke, don’t fix it” proponents will agree is broken and must be upgraded.

But PHP is a server-side software. It cannot be installed, updated or controlled by WordPress in any way.

You should upgrade PHP from your hosting control panel (not WordPress dashboard) if your hosting provider gives you this option. If you don’t see such a function in your hosting control panel, contact your hosting provider to upgrade the version of PHP your website uses.

Also, speaking of fonts, I’m also trying to change the font size of some text, but I can’t figure out how. When I input some new text, it is a little bit larger than all of the text surrounding it.

The default block-based WordPress editor applies the typography settings (including font size) to the entire block. So in this case, you don’t need to select the text: just ensure the cursor is anywhere in the paragraph block in question (which selects that block) and use the typography settings on the right column in the editor.

Here’s the full documentation: https://wordpress.org/documentation/article/paragraph-block/

The other problem I’m having is that when I try to edit the code manually at [ redundant link deleted ] with an editor NotePad++ (which usually works great) and if I try to make changes and view it with any browser, the image (a .jpg file) has disappeared. I don’t want it to disappear.

I don’t know what you’re editing in the NotePad++ editor, so I can’t talk about your experience.

But just understand that WordPress is a template-based content management system with the content of individual pages stored in the database. While you can edit your theme’s template files externally with a code editor like NotePad++, you cannot edit your website’s individual pages this way. There are no static HTML Pages to edit, all the content is stored in the database and rendered on the fly when a URL is requested.

So all content on your site must be updated from the WordPress dashboard, except for anything that’s placed inside a theme’s template files.

While you’re at all of this…

Your website displays a security warning to all visitors. You really need to address this.

The security warning is occurring because the website uses an SSL certificate that expired over 7 years ago, on 31st May 2018. That’s some serious maintenance there for you!
