Suddenly… Can’t access site – White screen

Hello @dynami,

It’s because theme or plugin you installed has a “Fatal error”, but you can’t see those errors cause your debugger is off. Try to delete last installed plugin or theme with your FTP account.

Of course, there can be more than one solve, so if this is not working, feel free to get more answers.

Thanks.

Hello
Thanks for the suggestion.

I have:

Renamed the plugins folder as *disabled plugins* so that none of them are loaded.
This didn’t solve the problem – same response.

Created a folder at
/public_html/alvechurchacousticroots/wordpress/wp-content/themes/*disabledthemes*

I’ve moved the currently selected theme to there.
This didn’t solve the problem – same response.

I moved recently updated themes to
/public_html/alvechurchacousticroots/wordpress/wp-content/themes/*disabledthemes*
This didn’t solve the problem – same response.

I noticed that index.php was recently updated and tried moving that.
This didn’t solve the problem – same response.

I’ve put everything back as it was.
This didn’t solve the problem – same response.

Thanks though.

Anyone else?

Here you can get more about “500 Internal Server Error” problems and how to fix them. Another one you can do is to enable debbuger. Go to WP folder and wp-config.php file, where you see

define('WP_DEBUG', false);

add this:

define('WP_DEBUG', true);
define('WP_DEBUG_LOG', true);

If your hosting provider enabled uploads you will get debug.log in your “wp-content” folder, and there will be more info about error you got.

@dynami, nice work, I’ve seen some movements here with site:

Notice: Undefined index: enabled in /home1/davidmh1/public_html/alvechurchacousticroots/wordpress/wp-content/plugins/newsletter-followup/followup.php on line 73

So, the problem is in your Newsletter plugin, but https://www.alvechurchacousticroots.co.uk/wordpress/wp-login.php is working now, so you can deactive this plugin and then try to get access to your site. If that works well, you should just update your Newsletter plugin.

Ok – Thanks for this
And in exploring I also found the error_log file.

Anyway….

On attempting the page load I get:

Fatal error: Call to undefined function convac_lite_wpml_filter() in /home1/davidmh1/public_html/alvechurchacousticroots/wordpress/wp-content/themes/convac-lite/functions.php on line 228

This would point to a problem with the theme.

I’ve therefore moved that theme to my *disabledthemes*folder.

Having done that I attempt a page load.
I get

Notice: Undefined index: enabled in /home1/davidmh1/public_html/alvechurchacousticroots/wordpress/wp-content/plugins/newsletter-followup/followup.php on line 73

This is only a notice and not a fatal error so shouldn’t stop anything loading.
But I have moved all the Newsletter modules to my *disabled plugins* folder

I’m now not getting any additional debug messages but still I get the white screen.

:-((

Wow!
I have a Login!!!!!
I feel a lot safer now!

Thank you –
I’ll see how far I get!

No problem, just try to disable as much plugin as you can, and test your site from plugin to plugin and try to change the theme, too. So if twenty-sixteen work with plugin, then theme is crashed somehow.

Give it a try, if you have any new info, I’m here to help you, of course.

Ok.
So with the brilliant help of @ristapk (see above)
I got into the admin page.
Tracked down the error as a problem with the Convac Lite theme.

Got in touch with SKETCH THEMES and tried their online chat.

Now then, I only have the Lite version installed so I was fully expecting support to be unavailable or patchy at least.

However –
I pasted the error message I was getting.
Within a couple of minutes it was confirmed that it was an error in a recent update.
Apologies were given and I was told an update would be out in 24 hours or less.
I was about to say “thank you”, but not hold my breath… I’ve heard those sorts of assurances….
And I was told…
“If you want an immediate fix…. Check your email”…
And there was a replacement functions.php file, which I uploaded and had my site back in seconds!

Now this is brilliant support!!!!!
Having had some dreadful support from my hosting company recently I can only say what a joy it is to find great assistance both here and in a commercial company.

THANK YOU WORDPRESS COMMUNITY!!!!!!!!!

Thanks @dynami, it’s my pleasure. WordPress community is great, I agree.
