All it says is "Error!"

no idea. Have you check error logs?

Hey Andrea_r,

Thanks for the reply.

I checked the error logs and no entry, but I did check the access logs and the GET request was there with a 200 code.

It might be a plugin that’s issuing this error. I grepped wordpress code for ‘Error!’ and it came up empty. Well there was an ‘Error!’ in wp-includes/ms-deprecated.php, but the HTML output was not the same. It was in the ‘graceful_fail()’ function. I will have to do more research on this.

Thanks!

Try a grep for letter-spacing: 0.5px but … obviously turn off all the plugins and see if it magically works.

Hey Ipstenu,

I grepped for letter-spacing: 0.5px and letter-spacing and I didn’t find the same code.

Unfortunately, I can’t deactivate any plugins as its a live install with quite a few sites on it.

Thanks!

Try a smaller export? Maybe limit it to this month or something…

Well guys I figured it out! Thanks everyone for the help!

The culprit was the WP-DownloadManager plugin.
I just changed the 2nd line (the if statement) from this…

<?php
if($_GET['download']!=''){
    $data = DB::getById('ahm_files',$_GET[download]);
?>
<style>
*{
    font-family: tahoma;
    letter-spacing: 0.5px;
}

input,form,p{
    font-size:9pt;
}
form{text-align:center;}
</style>

to this…

<?php
if($_GET['download']!='' && is_int($_GET['download'])){
    $data = DB::getById('ahm_files',$_GET[download]);
?>
<style>
*{
    font-family: tahoma;
    letter-spacing: 0.5px;
}

input,form,p{
    font-size:9pt;
}
form{text-align:center;}
</style>

It looks like this plugin relies on $_GET['download'] and is expecting this to be an int( id ). WordPress’ export function uses $_GET['download'] as a boolean. I have sent an email to the plugin owner.

Thanks again!

oops…

Looks like I made a mistake. It wasn’t the WP-DownloadManager plugin, it was the “Downlodable File Manager” plugin. I’m such a tool!!

I can see that happening… They both play with the download settings…
