Fatal error: Uncaught Error: Undefined constant “AI1WM_MAX_FILE_SIZE”

Hi there,

I just swtiched to a new server with php 8.x.
My best guess it has something todo with it, but I’m just guessing.

I’ve installed a fresh WP 6.2.2, further I’ve installed the newest AI1-Migration + Pro Version and activated them. Then when I click on “AI1-> Import” it results in the following debug log:

Fatal error: Uncaught Error: Undefined constant "AI1WM_MAX_FILE_SIZE" in /opt/app-root/src/web/wp-content/plugins/all-in-one-wp-migration-unlimited-extension/lib/controller/class-ai1wmue-main-controller.php:277 Stack trace: #0 /opt/app-root/src/web/wp-includes/class-wp-hook.php(308): Ai1wmue_Main_Controller->enqueue_import_scripts_and_styles() #1 /opt/app-root/src/web/wp-includes/class-wp-hook.php(332): WP_Hook->apply_filters() #2 /opt/app-root/src/web/wp-includes/plugin.php(517): WP_Hook->do_action() #3 /opt/app-root/src/web/wp-admin/admin-header.php(118): do_action() #4 /opt/app-root/src/web/wp-admin/admin.php(239): require_once('...') #5 {main} thrown in /opt/app-root/src/web/wp-content/plugins/all-in-one-wp-migration-unlimited-extension/lib/controller/class-ai1wmue-main-controller.php on line 277

Question(s):
– Is this really related to php 8.x; can someone confirm this please.
– Is there anything I can do to get it working with php 8.x?
– Or is this related due to some file/folder permission?

Really looking forward, need some help on this one.
Thank you @all
