Question

1C-Bitrix

I did a System Check, and there are 4 errors in the "Database Structure", please tell me how to fix them?

Answer 1

You can correct the field types in the admin or copy it
and execute it one by one in the sql console (/bitrix/admin/sql.php?lang=ru&del_query=Y).
* in case the contents of the fields get corrupted, make a full backup of the entire site, plus, if possible, a backup of the database with one file without compression, plus mysqldump to be sure
