Thank you, Steve, that helped track down the problem with enabling the module. Per the error logs, it seems that "ShippingEasy needs the Multibyte String PHP extension" After enabling that PHP extension, I was able to enable the module.

However, the problem with the 500 error still exists with the General Settings page and now, after enabling the module, with the Congifuation page of the Module. Both of which call the /admin/configuration.php file.

The error log does show an issue with that file:

PHP Fatal error: Class 'XCEmailFormat' not found in /home/theapron/public_html/admin/configuration.php on line 1474

Line 1474 shows:
$smarty->assign('email_extended_validation_regexp', func_email_validation_regexp(XCEmailFormat::EXTEND ED));

This is indeed a part that was added from the ShippingEasy module.

Of course, it all doesn't mean much to me, because I don't know all of the coding. Does it mean anything to you?

Thanks for the help!
