Email authentication errors (possibly) resolved by removing depreciated php function?

I was getting email authentication errors recently and noticed that there was an error in my server log about a depreciated php function (as of PHP 7.4.0) called get_magic_quotes_gpc(). I simply removed that and now the emails are going through again and no errors logged. Might this function do anything that I should be aware of that could be causing other problems or do you think it's safe to simply remove? Thanks!

It is safe to remove. It is a really old feature that I would always recommend having turned off and has been turned off by default for more than a decade.

okay, thanks. It's in all of the email templates that DA generated, like "webassist/email/templates/WebAssist-Default/Blank.php."

The code looks like this:

<?php
foreach( $_POST as $pkey => $pval ){
  if (!RemoveValue($pkey,$remove,$removeBegins,$removeEnds,$removeIncludes))  {
	  if (get_magic_quotes_gpc()) $pval = stripslashes((is_array($pval)?implode(", ",$pval):$pval));
?>
					<tr valign="top">
                    	<th style="font-size: 12px; width: 134px; text-align: right; padding: 3px 10px 3px 3px; font-weight: bold;"><?php echo(str_replace("_"," ",$pkey)); ?>:</th>
						<td style="font-size: 12px; padding: 3px;"><?php echo(str_replace("\n","<BR />",(is_array($pval)?implode(", ",$pval):$pval))); ?></td>
					</tr>
<?php
  }
}
?>

I just removed the part that says "if (get_magic_quotes_gpc())" and the email errors went away.

Yes... we have already removed that line in the most recent version of the extension.

I've got the latest version installed and it's still inserting that into my email templates.

I checked and the code definitely isn't there in the latest version. Perhaps your files aren't being overwritten. Are you trying it on a new page? Did you delete the old file first? Maybe your re-installation didn't work properly.

I'm seeing this in a new file with a new project in DW, so it would have nothing to overwrite. The file I downloaded and installed is DataBridge_235.zxp. Is that the latest version? Is there a way to tell which version is installed from within the app?

That is odd. And you reinstalled recently? That would appear to be the latest version, so I'm not sure how that is happening. I checked the source code for the project and that code was removed. If you want to set up a screen sharing session I could go in and see what is going on.

That would be great. I'm pretty much around today and tomorrow. Let me know if either works for you.

Just call me using the number at the bottom of every page of this website when you are available and I should be around most of the day tomorrow.
