In the new version, such errors began to appear in the event log:
Messenger Worker Message Failed: /new_site/public_html/concrete/vendor/symfony/messenger/Middleware/HandleMessageMiddleware.php:80 Handling “Concrete\Core\Page\Command\ReindexPageCommand” failed: An exception occurred while executing ‘SELECT * FROM btAccordionEntries WHERE bID = ? order by sortOrde’ with params [419]:
SQLSTATE[42S22]: Column not found: 1054 Unknown column ‘sortOrde’ in ‘order clause’
In the database table, this column is called ‘sortOrder’.
This error is related to the filling of the inserted Accordion block.
In version 9.0.1, which was installed on an external server, the database is constantly broken. For example, if the text contains the symbol “И” (Russian capital letter I).
