Found it! Oooof! https://codex.www.ads-software.com/Installing_WordPress

“5)If your text editor saves as Unicode, make sure it adds no byte order mark (BOM). Most Unicode-enabled text editors do not inform the user whether or not it adds a BOM to files; if so, try using a different text editor.”

In my case wp-config.php had been saved as UTF-8-BOM instead of just UTF-8. So it was quietly adding a BOM tag to the beginning of the output!

Hope this helps someone else out there. Ben thanks again for a great plugin.

Ben, hi, thanks for your time. To reaply to your questions :

Wordpress : Version 5.1
WP Document Revisions : Version 3.2.1
Does the problem occur even when you deactivate all plugins and use the default theme? YES

I’ve traced the problem to this :
/web/wp-content/plugins/wp-document-revisions/includes/class-wp-document-revisions.php
Line 1007 : readfile( $file );

Apparently at this point a 3 character “BOM” is added to the beginning of the files ouputted.

Txt and PDF files are still readable. Office files are not.

Server details/phpinfo are here : https://cenatho3.encours.fr/siteinfo.php

Lots of stuff in Google about this but no solution. I’ve tried changing the content-type and code-page (from UTF-8 to Windows) etc but it always outputs the BOM.

Any idéas welcome. TIA.

Me too. I’ve just put the clients site on line, so changed the URL. Any new form I create just gest stuck. I’m not using WP-Super Cache. Even this 1 line forme :

Just to complete @cheetah182’s remark, in the root directory of the plugin, in just-variables.php line 55 you need to update this function

function jv_get_variable_value( $var ){
//$values = get_option(‘jv_values’);
$values = get_option(‘jv_variables’);

if( !empty($values[$var]) ){
//return $values[$var];
return $values[$var][‘default’];
}

return NULL;
}
