Hi there,

A blank white screen?

Or a blank screen that still looks like you are in the admin?

Either of those will likely be a fatal error being thrown and that should be stored within the error logs, we’ll need that error to troubleshoot this further.

Your host will usually have a section within your control panel to view errors thrown on the site.

Or, if you have FTP access I can tell you how to enable logging within WordPress to view them separately?

Usually, they will be logged within root.

Edit wp-config.php within the root directory.

In that you’ll find:

define( 'WP_DEBUG', false );

Replace that single line with this snippet:

Once done, retrigger the error and it should then be logged in /wp-content/debug.log

Ok, so set this:

define( ‘WP_DEBUG_DISPLAY’, false );

To be true.

The error should then display on the page itself (note any notices/errors displayed on your sill will also be visible on the front end whilst the above is active).

Then your server isn’t logging errors (the above can be overridden by your host).

Try with:

define( 'WP_DEBUG_DISPLAY', true );

Or just simply using the single line of:

define( 'WP_DEBUG', true );

Either of those should set the server to display the errors on the page itself.

Wait, so are you getting a blank screen or Error 402?

Error 402 isn’t a code error so it won’t log anything within the PHP error logs.

Sounds like Vivaldi doesn’t handle 402 errors correctly then.

Try adding:

define( 'EE_USE_OLD_CSV_REPORT_CLASS', true );

Somewhere above:

require_once(ABSPATH . 'wp-settings.php');

That will switch EE to a different export system, it’s old one we’ve since replaced but I’d like to see if that works.

Firefox now produces a report, but it includes all registration records, not the filtered list as displayed when the report was requested.

Yeah the old CSV report won’t support the new filtering method we use.

It may always have done this, I don’t know as I haven’t used it before, but it’s not what I had hoped for.

It’s sort of always done the above, the ‘Filtered’ report was a separate button when we used the above system so the current version won’t filter down.

The idea behind testing the above wasn’t for a fix but to see how the server handled the request itself.

Vivaldi no longer gives a 402 error, it just does nothing when the CSV Report button is pressed.

I can’t trust/rely on Vivaldi’s response as it stands, it could be getting another 402 and again just handling it differently. Or it could be blocking the download if if the request is being made over HTTPS and the return is HTTP.

If you open up Dev Tools (assuming it has one) and click the button, the network tab should show you more details.

So, right now I’m suspecting something going on with your host. For some reason, it doesn’t like the request for the ‘batch’ processing we use in the ‘new’ export system.

Who are you hosting with?

November 22, 2022 at 2:04 pm

The DevTools Network tab window just flashes briefly when I click to generate the CSV, but no activity is shown – but I have never used this tool before so don’t know what to expect.

Open dev tools before you click the button.

At the top make sure ‘Preserve log’ is enabled:

When you click the button you’ll see all of the requests your browser makes on that click.

That will give you more details about what is happening.

I have temporarily whitelisted our site, freerotation.com, in both Firefox and Vivaldi privacy and security seetings, but it makes no difference

I don’t think this is a browser issue and whitelisting won’t stop the above.

Most browsers now block downloads if they are streamed via HTTP when the site is HTTPS.

We are hosting with Inventive Hosting https://www.inventivehosting.co.uk

Hmm, never heard of them.

I’d recommend opening a ticket with the them an ask them to check if anything s blocking the original request. As your the only person reporting this (nothing has changed within the export system in a long time now) I suspect this is some kind of server config issue.
