Error: fn.common.php on line 2642

I am seeing the following error all over my site:

<br />
Warning: preg_replace_callback(): Requires argument 2, '', to be a valid callback in /home/lehmannr/public_html/app/functions/fn.common.php on line 2642<br />
%m/%d/%Y<br />

```<br />
<br />
I am not sure how to fix this? I am running CS-Cart 4.0.2 and it was working fine with CS-Cart 4.0.1. I just upgraded it via the admin panel and now this happened. By the looks of the error, it seems like fn.common.php is trying to call a command that is missing. I wonder if the upgrade delete or moved it.<br />
<br />
I am experiencing a ton of issues with CSCart v4. Lots of bugs. Tons of problems. Helpdesk wants to charge me to fix their mistake. Somebody please help me.

There are a considerable amount of changes to fn.common.php from 4.0.1 including the line that it is specifying. I would reupload that file and see what happens.


return preg_replace("/(%.)/e", "\$s['\\1']", $format);


return preg_replace_callback("/(%.)/", function($m) use ($s) {
if (isset($s[$m[1]])) {
return $s[$m[1]];
} else {
return false;
}, $format);

Edit: I do not see the error on your site.

Apparently it was due to “eAccelerator” not being disabled with my host. They disabled it, now it works.

It took CS-Cart three days to write back and they charged me to tell me to tell my host to can it, but it works.

Upset but glad it's over with.
