Hoping it would fit
But when I submitted the edit I got the same error.
Data too long for column 'POST_BODY' at row 1
I was easily able to create a text (UBBCode Only) post over 16 MB on stock PHP 7.4 and MySQL/MariaDB 10.4.13 server settings.
Over 16 MB on my Linux DEV site
Over 20 MB on my Windows DEV site
Limited to only 64 KB on Linux UBBCentral.com
Test/confirm the following items:
1/ the database you've updated multiple times over the past decade, was updated correctly and matches stock UBBT 7.7.4 data types and sizes
2/ the server you're working on has its php -OR- mysql config settings configured correctly for your needs. there are many possible things to search your customized settings for, two of them could be "page-size" and "buffer".
Gizmo mentioned point 1 earlier in this topic. For point 2 you need to confirm your settings are stock or within range for your specific needs:
I dont know anything about your server's exact customizations, but I would sugest you either revert those settings to stock and test again, or perform further research on what is needed. Custom server tuning is beyond the scope of the the ubbcentral support forums.
