I installed 2.1.0 but nothing but blank white page for Admin

I installed 2.1.0 with PHP 8.3 on my server. It has been maybe 3 years since I installed Zen Cart it for anyone else. I did it as a upgrade to my own website.

The front end displays normally, see pic following. Database up-graded seemed ok. But everything I tried including reloading the admin files, then getting another download and reloading the admin files again. I just cannot get nothing but a blank white page for my admin URL! When I "view source" of the blank page, it says "Line Wrap" up in the left hand corner with a number 1, and nothing on the page otherwise. No 404 error.

I checked the 2.1.0 Logs, and nothing shows up with issues for the admin area. When I check my servers error logs, it shows no errors for my ZenCart folder either. I also checked with a PHP file with this code in it to make sure I was using right path: <?php$p = getcwd(); echo $p; ?> And I have my my correct path in both of the configure.php of: /home/MyServer/public_html/MyShopFolder/

I don't know what else to try when I don't get error messages when the URL to my admin is blank? Reloading all files and folders in the admin area twice just did not help.

I had a similar issue upgrading to v2.01. My problem was the Recent Orders Dashboard Widget taking far too long to load.

In your_admin/includes/modules/dashboard_widgets/RecentCustomersDashboardWidget.php, lines 16-17:

$includeAttributesInPopoverRows = $includeAttributesInPopoverRows ?? true;
$maxRows = $recentOrdersMaxRows ?? 25;

Change line 16 true to false and line 17 change 25 to 10.

Thanks for reply. I'm going to check that out. But, funny thing, a few hours later I tried something. At first though, after the install, I renamed the admin folder giving it a 6-digit name all small letters. Then tried to login several times, and with different Browsers too. Always the white screen. Then I posted the above for help. A few hours later, frustrated, I changed the 6-digit name to a different 6-digit name, and also all small letters again too. Then I tried that on the admin url, and guess what? The login page showed up!! Why...I have no idea.

I also just had that happen. I tried changing the admin name, did not work. I do not see those lines of code in your_admin/includes/modules/dashboard_widgets/RecentCustomersDashboardWidget.php

Any ideas?

Sorry its the Recent Orders widget:

your_admin/includes/modules/dashboard_widgets/RecentOrdersDashboardWidget.php

Hi ChuckPhilips, I tried your suggestion, it didn't work. Here is message I'm getting in my error log:

I dont think thats related. It's something to do with the DisplayLogs plugin, apparently missing a constant define. Check the language file for that plugin.

Thank you, you were correct. For some reason I had both versions V3.0.0 and V3.0.2 in my folders. Once I deleted V3.0.0, it worked.
