WHEN WORDPRESS MIGRATIONS GO WRONG

WordPress is a fantastic CMS with so many plugins and ways to extend the
functionality, there’s not much bad to say about it – which goes some way to
explain why so many of us are using it to build our own and other’s websites.
That said, it’s a technology like any other and sometimes things go wrong. Of
course, they only ever go wrong when you least want them to, so here’s a quick
summary of the three most common errors that I come up against when moving
WordPress sites.

Why would anyone be moving a WordPress site you ask? Well, you might be moving
hosts (yes, that can be done!) or you might have been working on a local or
development copy so you can test and verify a major update without disrupting
the main site. For those of us working away on the backend, moving WordPress
sites is just one of those day-to-day things.

But that doesn’t mean it’s foolproof! Three most common issues I see are:

 * Plugin issues causing conflicts, resulting in the illusive error: “The site
   is experiencing technical difficulties.”
 * Images not being displayed on pages, even when you can see they’re there in
   the media library and nothing has changed (except for the site having moved,
   of course.)
 * Redirect errors and stray URLs preventing the site from loading or displaying
   correctly.
 * Problems with the links in the database or connection info in the
   wp-config.php file resulting in the “Error Establishing a Database
   Connection” error.

Let’s address these one-by-one.


FIX THE WORDPRESS ERROR: “THE SITE IS EXPERIENCING TECHNICAL DIFFICULTIES.”

This one, while utterly terrifying (it literally says nothing useful about the
issue you are facing) is actually one of the easiest to fix. If you get this
error you will often find that you can login to the admin dashboard but not see
any of the pages on the site. To test this, type /wp-admin after your domain and
see if you can login. Usually you can – which is good because it means the fix
I’m about to describe will work.

If you get this error, you need to be able to access the WordPress files on the
server OR to be able to access the admin dashboard.

If you can access the dashboard, you need to deactivate all the plugins. Then
reactivate them one at a time. Each time you reactivate one, test the site (I
usually have this open in a separate tab and refresh the page to see) then
continue, adding them one at a time until the site breaks. When you find the
offending plugin(s), you can usually resolve the issue by uninstalling then
reinstalling the plugin. It’s super easy to do.

Another way – and by far the fastest and easiest (given the number of plugins
you could be facing) to deactivate all the plugins is to change the name of the
plugins folder, which you can get to via cPanel file manager or via FTP. Just
rename it – it doesn’t matter what, but logically “pluginsOFF” or “zplugins”
works – then test the site, see if it works (see if you can login to the admin
dashboard, if you couldn’t before) then rename it back to plain old “plugins”.
Once this is done you do exactly as described above: activate them one at a time
’til you find the culprits, then remove and reinstall them.

Not so bad, eh?

Now for the next one.


IMAGES DON’T DISPLAY AFTER WORDPRESS SITE MIGRATION

This is one of my favourites; Okay, it’s not, but whenever this happens it
always takes me a few minutes to remember how easy and fast the fix is.

First, navigate to Settings and then Permalinks, then change the selection from
whatever setting you have (usually Post name) to Plain.

Fixing the Permalinks

Save this setting (scroll down and click the button to save) then change it back
to Post name. Check your site (refresh the page or check in an Incognito
browser, if you’re not sure it’s refreshing) and many times out of 10 this will
have fixed the issue.

But sometimes it won’t! In this case you may well find the issue is some stray
links in the database – so onto the next fix.


FIX REDIRECT ERRORS AND STRAY URLS THAT STOP YOUR SITE LOADING OR DISPLAYING
CORRECTLY

Now you’re into database editing territory, so you might want to call on tech
support (via your host) or a friendly techie (like me) to get this part done.
But it can be done and it needn’t be terrifying – just as long as you make a
backup first.

With your backup in place, login to PhpMyAdmin and find the database you are
using for your live website. Then just search EVERY table for the URL you used
for your development site (or the old site name if you’ve changed the location
of it) and the live site. There are some simple SQL queries to use for changing
the URLs, but do remember to try every permutation of the URL you can think off.
I once had a problem with a site and found a bunch of old URLs addressing my
local installation (localhost), which had long since been deprecated! Work your
way through these and you should find you’re on your way to a fully functioning
site, unless…


FIX A WORDPRESS “ERROR ESTABLISHING DATABASE CONNECTION” ISSUE

First up, don’t panic. Despite being monumentally unhelpful this message is also
another relatively simple fix. You need to check that your database details in
wp-config.php match the details of your actual database and with those two
things syncronised, usually you’re good to go.

You’ll find the database name in PhpMyAdmin and the wp-config.php file in your
site’s WordPress folder. If in doubt try changing the user password, which you
can usually do through MySqlDatabases in cPanel. Make sure your user has full
permissions too.

If you get this far and your site still isn’t loading, it’s definitely time to
reach out for help, even if the “IT Guy (or Gal)” that comes online to fix it
does just one of the four things above and they work (yes, this often happens!)

If you need more detailed explanations for any of the fixes above I can do more
step-by-step description, but if you know your way around WordPress this should
tell enough to get your site up and running again. I know it’ll be a useful
reference for me the next time a site migration goes “pop”!
