Presume this function is for administrators to leave notes for each other. We could use it to report any new wrinkles or hazards we discover without needing to email each other all the time. Will also be useful for future administrators to read themselves in  – avoid them having to go for more training. For instance, notes from our training day, and bits discovered since, not in any particular order.

1.  There are limited pages we need to use – Pages, Media, Events, Appearance/menus, that’s about all.  We should leave alone Editor, Themes, Settings, Tools.  We should NOT go into “plugins”.  I did so and in my ignorance caused a bit of bother!

3. Procedures for creating a sub-gallery – “add media” -select “Create gallery” (top left corner) – select items you need – insert names in “caption this image” – insert.

5. Access for reaching the Backend system for administrators ie, type:   /wp-admin/ after web address.

6. Problem when WordPress upgraded to 4.9.2.   Jan/2018.  Message on site:”Warning: preg_match(): Compilation failed: unrecognized character after (?< at offset 4 in /web1/user/website/wp-includes/wp-db.php on line 1657″.   Discussion on WP Forum https://wordpress.org/support/topic/site-down-after-4-9-2-upgrade/page/2/#post-9878030.  Solution was to “Just add @ symbol at the front of the line in wp-db.php – $result = @preg_match( $pattern, $host, $matches ); To make the fix advice

“Open files 4.9.2 files on the server then look for the folder names “wp-includes”. Open “wp-includes” and near the bottom of the files listed, you will see wp-db.php
Open wp-db.php and around line 1657 you will see the line of code to amend.  If you don’t have a file editor, try something free such as Notepad++ as it lists line numbers.  Fixed by Joe Wood -Joe@mnbcomputing.co.uk 07825 398566.   Access to the files is via the hosting site is, which is: www.easily.co.uk
