OK, I got it to work. If you are familiar with manual mod installation this should get you through it.

Also, if you already have glow shadow undo redo on your forum you have to watch it when you add this one. To install this one after undo, etc. search for a different line of code in post.pl.
Admin center mod asks you to search for

<div style="width: 484px; clear: both;"><div style="width: 391px; float:left;"> 

Instead search for

<div style="width: 530px; clear: both;"><div style="width: 437px; float:left;"> 

and replace that.

Back to the original problem, you only need to change one thing.

Sources/Register.pl
Listed Search For:

<td valign="middle"><input type="text" maxlength="60" name="email" value="$tmpregemail" size="45" /><input type="checkbox" name="hideemail" value="checked"$hidechecked /> $register_txt{'721'}
</td> 

Instead Search For:

<td valign="middle">$aedomains <!-- ### Distilled Email Domains mod ### -->
<input type="checkbox" name="hideemail" value="checked"$hidechecked /> $register_txt{'721'}
</td> 

Replace with THIS

<td valign="middle">$aedomains <!-- ### Distilled Email Domains mod ### --><br />~;
if(($default_HideMail == 1 && $default_HideMail_val == 1) || $FORM{'thideemail'} == 1) {
	$hidechecked = qq~ checked="checked"~;
}
else {
	$hidechecked = "";
}
$yymain .= qq~
	    <input type="checkbox" name="hideemail" value="checked"$hidechecked /> $register_txt{'721'}
	</td> 

I also had a problem with the buttons loading funny after installation. This was duo to a /br in the button list. The problem is just below where you need to modify the above code if you have it too. Just scroll down and look through the document.write list and make sure there is not a br/ symbol after any of them. If so remove it.

I hope that's enough to get the you through it should the need arise. This will only work for manual installation. I haven't found any errors yet, I think it works fine. But it would be good if someone that knows what their doing makes sure its an acceptable fix.

BACK EVERYTHING UP BEFORE YOU MAKE CHANGES. And keep them around for awhile, I don't know what I'm doing. But it seems to be fine.

Hi douglasrm

Did you add any other mods or change any existing code?

When the mod looks for a string to replace it also looks for character spaces. If you have added or deleted a space then the code won't be found.

Have a look in the mod file, using a text editor, for the code that it is trying to find. You may be able to find it and compare it manually. If there is a small difference such as a missing space or one too many then you can just update the mod file to match what you have.

If there is a very big difference in the code then I don't recommend that you make any change.

Remember to backup all your files first.

I have that security update installed. Will this mod work for me?
