Joomla 4.3.1, T4 System 2.2.9, T4 Blank Template Bs5 1.1.8, ja_artsy 2.0.1
I started with the JA Artsy for J4 Quickstart. I dubbed the default style and edited the Site Settings->Logo Image to a logo jpg I have. The logo appears on the preview and when I choose to save at the top of the Site Settings I receive a "Save Successful" message at the bottom of the Site Settings window, but the setting is reverted back to the original. I tried with the T4 Blank Template Bs5 as well, same issue.
I can confirm that the new value was correctly written to /templates/t4_bs5_blank/local/etc/site/default.json. I've noticed that the Site Name and Slogan will properly save, until I add my logo image - then everything is reverted.
I found a couple of warnings in my php logfile
PHP Notice: Undefined variable: row in /var/www/artsy.test.org/htdocs/plugins/system/t4/themes/base/html/com_content/featured/default.php on line 68
PHP Notice: Undefined variable: rowcount in /var/www/artsy.test.org/htdocs/plugins/system/t4/themes/base/html/com_content/featured/default.php on line 70
It seems something isn't setup right. What should I check?
